Technical Field

[0001] This utility model is an integral precast box culvert formwork, belonging to the field of box culvert formwork. Background Technology

[0002] A box culvert is a culvert constructed with a reinforced concrete box-shaped pipe structure. A box culvert consists of one or more square or rectangular sections and is generally made of reinforced concrete or masonry, but reinforced concrete is more widely used. When the span is less than 4m, a box culvert is used. For pipe culverts, reinforced concrete box culverts are a cheaper alternative. The piers, abutments, and upper and lower slabs are all cast in the same manner.

[0003] Currently, existing monolithic precast box culvert formwork lacks a good overall structural reinforcement design, and its overall structural strength is poor after frequent assembly and installation. Therefore, this application proposes a high-strength monolithic precast box culvert formwork. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integral prefabricated box culvert template.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0024] 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.

[0025] Please see Figure 1-2 This utility model provides a technical solution: an integral precast box culvert template, including two front end plates 1, two side plates 2 and two cover plates 3. The front end plates 1, side plates 2 and cover plates 3 are detachably connected to form the entire box culvert template body. The side plates 2 and cover plates 3 are each composed of two split plates 4. The split plates 4 have reinforcing grooves 5 inside, and reinforcing steel bars 6 are placed inside the reinforcing grooves 5.

[0026] See Figure 1-3 The cover plate 3 is fixedly provided with an insertion plate 7 at equal intervals on one end face of the side plate 2. The side plate 2 has an insertion port 8 for inserting the insertion plate 7. The insertion plates 7 located farthest apart on the cover plate 3 are provided with mounting thread holes 9. The side plate 2 is also provided with mounting thread grooves 10 corresponding to the mounting thread holes 9. A long mounting screw is screwed into the mounting thread groove 10 and the mounting thread hole 9. First, the two cover plates 3 and the two side plates 2 are installed to form a rectangular template. The insertion plate 7 on the cover plate 3 is inserted into the insertion port 8 of the side plate 2. At this time, the mounting thread hole 9 on the insertion plate 7 corresponds to the mounting thread groove 10 on the side plate 2. The long mounting screw is screwed into the mounting thread groove 10 and the mounting thread hole 9. The long mounting screw is electrically rotated with the drilling machine. The long mounting screw is a screw rod, and its end has a quincunx hole that matches the drill bit of the drilling machine.

[0027] See Figure 1 and Figure 3The side plate 2 is fixedly provided with an insertion plate 21 at equal intervals on one end face of the front plate 1. The front plate 1 has an insertion port 22 corresponding to the insertion plate 211. The side plate 2 and the front plate 1 are installed by the installation parts. The two cover plates 3 and the two side plates 2 are installed to form a rectangular template. The rectangular template connects the two front plates 1. That is, the insertion plate 211 on the side plate 2 is inserted into the insertion port 22 on the front plate 1, so that the front plate 1, the two side plates 2 and the two cover plates 3 can be connected to form an integral precast box culvert template.

[0028] See Figure 1 , Figure 4 and Figure 5 The mounting components include a horizontal plate 13, with fixed long rods 14 fixed on both sides of the bottom end of the horizontal plate 13. The top of the front plate 1 has a through groove 15 connecting to the uppermost insertion port 12. The front plate 1 also has a connecting groove 16 inside, and adjacent insertion ports 12 are connected to each other through the connecting groove 16. The fixed long rods 14 have threaded corresponding holes 17, and the front plate 1 and each insertion port 12 have corresponding secondary threaded corresponding holes 18. The above realizes the connection of the front plate 1, the two side plates 2 and the two cover plates 3. Then, the fixed long rod 14 on the transverse plate 13 is inserted into the insertion port 2 12 through the connecting groove 16. Because of the design of the connecting groove 16, the adjacent insertion ports 2 12 are interconnected. Therefore, the fixed long rod 14 is inserted into the insertion port 2 12 and the connecting groove 16. At this time, the threaded hole 17 on the fixed long rod 14 corresponds to the secondary threaded hole 18 on the front end plate 1. The additionally configured installation long screw is screwed into the interior, which can fix the fixed long rod 14 and achieve the overall fixation. The installation of the entire precast box culvert template is completed.

[0029] See Figure 1 , Figure 4 and Figure 5A horizontal connecting plate 21 is fixed between two horizontal plates 13. A vertical reinforcing plate 19 is fixed at the bottom of the horizontal connecting plate 21. The vertical reinforcing plate 19 and the side plate 2 have corresponding mounting holes 20. Corresponding blocks 22 are fixed at both ends of the horizontal connecting plate 21. Corresponding slots 23 for the corresponding blocks 22 to be inserted are opened on the horizontal plates 13. Corresponding blocks 22 and the horizontal plates 13 have corresponding secondary mounting holes 24. Before the aforementioned fixed long rod 14 passes through the connecting slot 16 into the insertion port 12, the horizontal connecting plate 21 needs to be installed between the two horizontal plates 13 in advance, that is, the horizontal connecting plate 21 needs to be installed. The corresponding block 22 at the end of the connecting plate 21 is inserted into the corresponding groove 23 on the transverse plate 13. At this time, the secondary mounting hole 24 corresponds, and the screw is inserted into it to fix the transverse plate 13 and the transverse connecting plate 21. After this step of installation, the fixing rod 14 is inserted into the insertion port 12 from the connecting groove 16 to continue the subsequent fixing work. After the subsequent work is fixed, the designed vertical reinforcing plate 19 contacts the outer surface of the side plate 2, and the vertical reinforcing plate 19 corresponds to the mounting hole 20 on the side plate 2. The screw is inserted. The design of the vertical reinforcing plate 19 further improves the overall strength of the box culvert template.

[0030] In practice, the precast box culvert template is divided into two front end plates 1, two side plates 2, and two cover plates 3 to facilitate subsequent assembly and transportation. After transportation to a suitable location, the template is installed as a whole to form the precast box culvert template. The two side plates 2 and the two cover plates 3 are each composed of two separate plates 4. The two separate plates 4 are joined together. Specifically, reinforcing steel bars 6 are first inserted into the reinforcing groove 5. Therefore, after the two separate plates 4 are joined together, the side plates 2 and cover plates 3 contain reinforcing steel bars. After assembly and installation, the overall structural strength is good.

[0031] The long mounting screws and bolts used during installation have their heads screwed into the corresponding threaded holes. These threaded holes are the mounting thread groove 10, the corresponding hole 18 of the secondary thread, and the mounting hole 20 on the vertical reinforcing plate 19. This prevents the heads from being exposed. Finally, a sealing rubber block can be inserted into the threaded hole. The rubber block can be pried out of the threaded hole later with the help of tools. The design behind the rubber block is mainly to block the threaded hole.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
