Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the production and processing of rainwater box culverts, specifically a folding and telescopic support device for the outer template of a rainwater box culvert. Background Technology

[0002] A box culvert is a culvert constructed using reinforced concrete box-shaped pipe sections. It consists of one or more square or rectangular cross-sections, typically made of reinforced concrete or masonry, though reinforced concrete is more widely used. Box culverts are often used when the span is less than 4 meters. For pipe culverts, reinforced concrete box culverts are a cheaper alternative, with piers, abutments, and upper and lower slabs all cast uniformly. Rainwater box culverts are underground drainage facilities in urban drainage systems used to collect and transport rainwater. They are usually enclosed box-shaped structures made of reinforced concrete or brick. They consist of a base slab, side walls, and a top slab, and are rectangular or circular in shape. They are constructed either by on-site casting or by prefabrication in a factory and then transported to the site for assembly.

[0003] During construction, templates need to be erected and effectively supported. A search revealed Chinese patent application CN202410314651.1, which discloses an aluminum template support device beneficial for concrete pouring. Belonging to the field of concrete pouring construction technology, it includes multiple parallel-distributed aluminum alloy templates, as well as installation frames, separators, connecting blocks, assembly locking mechanisms, connecting plates, and diagonal bracing mechanisms. This invention, through the connection process of the connecting blocks and connecting grooves, simultaneously performs the insertion of the connecting blocks and U-shaped rods, the insertion of the connecting racks and limiting holes, and the alignment of the fixing sleeves and protective sleeves. Through the threaded locking between the locking bolts and the fixing sleeves, and the docking action between the locking bolts and the protective sleeves and the locking bolts, the two installation frames are doubly locked through the inner sidewalls and the outer perimeter. This ensures stable assembly of multiple installation frames, effectively improving the stability of the aluminum alloy templates during assembly and installation, greatly guaranteeing the flatness of adjacent aluminum alloy templates and installation frame surfaces. It is easy to operate and highly stable.

[0004] However, the support of the external formwork is crucial during construction. The aforementioned technical solutions and existing external formwork support devices for rainwater box culverts have shortcomings. From a design and construction perspective, they lack versatility, requiring customized support devices for box culverts of different sizes and specifications, increasing design and manufacturing costs. Furthermore, existing support devices are expensive, encompassing costs for transportation, installation, dismantling, and other aspects, thus increasing the overall project cost.

[0027] 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.

[0028] Please see Figure 1-3 This utility model provides a technical solution:

[0029] A folding and telescopic support device for the outer formwork of a stormwater culvert includes:

[0030] Main structure; The main structure includes a base plate 1 and a side plate 2. The side plates 2 are symmetrically arranged on both sides of the base plate 1. The side plates 2 are rotatably mounted on the base plate 1 so that the side plates 2 can be folded on the base plate 1. The base plate 1 is provided with a boss 10 to fix the flipping angle of the side plates 2.

[0031] It also includes a fixing structure for fixing the outer formwork of the rainwater culvert; the fixing structure includes a clamping plate 4 located on one side of the side plate 2 and an adjusting screw 5 threaded onto the side plate 2. One end of the adjusting screw 5 is fixedly connected to one side of the clamping plate 4, and the other end of the adjusting screw 5 is welded with a rotating wheel 6. Two sets of guide rods 7 are symmetrically arranged on both sides of the adjusting screw 5 on the clamping plate 4, and the guide rods 7 are slidably inserted into the side plate 2.

[0032] The side plate 2 of the main structure is rotatably mounted on the base plate 1, and the folding of the side plate 2 on the base plate 1 is achieved by utilizing the characteristics of the rotatable connection. In use, the side plate 2 is unfolded to a vertical angle, and the flip angle of the side plate 2 is fixed by the boss 10 on the base plate 1. In the fixing structure, rotating the wheel 6 at one end of the adjusting screw 5 causes the clamping plate 4, which is fixedly connected to the adjusting screw 5, to move. The guide rods 7 on both sides of the clamping plate 4 slide on the side plate 2, playing a guiding role and ensuring that the clamping plate 4 moves smoothly, so that the clamping plate 4 abuts against the outer wall of the rainwater culvert outer template for support.

[0033] The foldable design of side plate 2 reduces space occupation when the device is not in use, facilitating storage and transportation. The fixing function of the boss 10 at the angle of side plate 2 ensures that side plate 2 remains stable when supporting the outer formwork of the rainwater culvert. The fixing structure, through the cooperation of adjusting screw 5 and clamping plate 4, allows clamping plate 4 to extend and retract on one side of side plate 2, enabling flexible fixing of the outer formwork of the rainwater culvert, adapting to different construction needs, and improving the versatility of the device.

[0034] For further details, please refer to Figure 1-3 :

[0035] A connecting block 3 is provided on the base plate 1. The lower end of the side plate 2 is rotatably connected to the connecting block 3. A triangular reinforcing plate 8 is symmetrically provided on the base plate 1. A limiting block 9 is provided at the lower end of the reinforcing plate 8. The boss 10 is shaped like a convex character. Limiting surfaces 11 are provided on both sides of the boss 10. When the side plate 2 is rotated 90 degrees, the bottom surface of the limiting block 9 abuts against the limiting surface 11.

[0036] The lower end of the side plate 2 is rotatably connected to the connecting block 3 on the base plate 1, providing a support point for the rotation of the side plate 2. When the side plate 2 is rotated to ninety degrees, the bottom surface of the limiting block 9 at the lower end of the reinforcing plate 8 will abut against the limiting surfaces 11 on both sides of the boss 10. This is based on the limiting principle of the mechanical structure, using the contact between the limiting block 9 and the limiting surface 11 to prevent the side plate 2 from rotating further.

[0037] Connecting block 3 ensures the flexibility and stability of the rotation of side plate 2. Triangular reinforcing plate 8 enhances the overall structural strength of the device and improves its stability when subjected to external template pressure. The cooperation between limiting block 9 and limiting surface 11 precisely limits the maximum rotation angle of side plate 2 to ninety degrees, keeping side plate 2 stable at this angle and providing reliable support for the external template.

[0038] In addition, please see Figure 1 , 4 And 5:

[0039] The base plate 1 includes a left plate and a right plate, which are connected and adjusted by a telescopic screw and a sliding rod 16. The ends of the left and right plates that meet are both convex in shape. One side of the left and right plates has threaded grooves 17 corresponding to the telescopic screw. The telescopic screw includes a first telescopic screw 12, a second telescopic screw 13, and a cylinder 14. The first telescopic screw 12 and the second telescopic screw 13 are located at opposite ends of the cylinder 14. The threads on the first telescopic screw 12 and the second telescopic screw 13 are in opposite directions and are threaded into the threaded grooves 17 of the left and right plates, respectively. Multiple sets of sleeves 15 are arranged around the outer wall of the cylinder 14. The other side of the left and right plates has sliding grooves 18 corresponding to the sliding rod 16. The two ends of the sliding rod 16 are slidably inserted into the sliding grooves 18 of the left and right plates, respectively, and both ends of the sliding rod 16 are provided with limit plates.

[0040] The left and right plates are connected by telescopic screws and slide rods 16. The first telescopic screw 12 and the second telescopic screw 13 have opposite thread directions. In actual use, the cylinder 14 can be rotated by inserting a pry bar or a steel bar into the sleeve 15. Since the first telescopic screw 12 and the second telescopic screw 13 are respectively threaded into the threaded grooves 17 of the left and right plates, the left and right plates will move closer or further apart, thereby adjusting the length of the base plate 1. The two ends of the slide rod 16 slide within the sliding grooves 18 of the left and right plates, respectively, serving as guides and auxiliary supports. The limiting plate prevents the slide rod 16 from coming out of the sliding groove 18.

[0041] This design allows the length of the base plate 1 to be flexibly adjusted according to different sizes of the stormwater culvert, further improving the versatility of the device and enabling it to adapt to the external formwork support requirements of various specifications of stormwater culverts. Meanwhile, the sliding rod 16 and the limiting plate ensure the smoothness of the adjustment process and the reliability of the structure.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
