[0002] A box culvert is a culvert structure made of reinforced concrete or masonry, typically consisting of one or more square or rectangular sections. It is mainly used for spans less than 4 meters, serving as an alternative to pipe culverts, and offers advantages such as high structural load-bearing capacity and ease of construction.

[0003] In modern infrastructure, box culverts are widely used in urban drainage systems, highway interchanges, and water conservancy projects. For example, in the construction of sponge cities, box culverts serve as the backbone of the drainage network, effectively solving urban flooding problems. Culverts are an important engineering structure, playing an irreplaceable role in modern infrastructure due to their stability, load-bearing capacity, and construction flexibility.

[0004] In existing cast-in-place box culvert construction, steel formwork needs to be installed before pouring concrete. Traditional box culvert steel formwork is inconvenient to assemble and connect two steel formworks during construction, which requires a lot of manpower and time to lay the box culvert steel formwork, and the assembly speed is not good, affecting the overall construction efficiency. Therefore, this utility model proposes a prefabricated box culvert steel formwork structure that facilitates the assembly and connection of steel formworks. Utility Model Content

The hollow cavity inside the steel formwork body 1 forms the inner mold cavity 2 of the box culvert, thereby ensuring the normal use effect of the box culvert steel formwork after pouring.

[0025] For details on facilitating rapid positioning and assembly of the steel formwork bodies 1, please refer to the appendix of the instruction manual. Figure 1 as well as Figure 4 As shown, side formwork frames 6 are fixedly installed on both outer walls of the steel formwork body 1. Several sets of equally spaced assembly seats 3 are fixedly installed on the outer walls of both front ends of the side formwork frames 6. Each set of assembly seats 3 is composed of two positioning blocks, with a distance between the two positioning blocks.

[0026] In order to ensure the proper connection with the mounting base 3, the outer walls on both sides of the tail end of the side mold frame 6 are fixedly installed with mounting wedges 4 that are compatible with the mounting base 3. Both the mounting base 3 and the mounting wedges 4 are provided with mounting holes 5 for positioning and connection.

[0027] With this structural design, when it is necessary to assemble two steel template bodies 1, the two template bodies 1 can be aligned and then the two steel template bodies 1 can be brought into contact end to end. At this time, the end surfaces of the two steel template bodies 1 will touch each other. During the end-to-end contact process of the two steel template bodies 1, the assembly wedge 4 at the tail end of one steel template body 1 can be inserted into the assembly seat 3 at the front end of the other steel template body 1, thereby completing the preliminary assembly connection work between the two steel template bodies 1.

[0028] After the assembly wedges 4 of the two steel template bodies 1 are positioned and connected to the assembly base 3, the assembly wedges 4 and the assembly holes 5 on the assembly base 3 are vertically aligned, as shown in the attached instruction manual. Figure 4 As shown, bolts for assembly are then installed one by one in several aligned assembly holes 5, thereby completing the quick assembly connection between the two steel formwork bodies 1. By operating in the above manner, the quick assembly and laying of the box culvert steel formwork can be completed, improving the construction efficiency of the steel formwork.

[0029] In this embodiment, a top mold frame 9 is provided at the top of the steel formwork body 1, and a bottom mold frame 10 is provided at the bottom of the steel formwork body 1. In order to facilitate integrated production, the steel formwork body 1, the side mold frames 6, the top mold frame 9 and the bottom mold frame 10 are all set as an integrated molding structure.

[0031] Furthermore, several evenly distributed secondary longitudinal reinforcing ribs 11 are fixedly installed on the inner wall of the top mold frame 9 by welding, and several secondary transverse reinforcing ribs 12 are fixedly installed between two adjacent secondary longitudinal reinforcing ribs 11.

[0032] Based on the above structure, this utility model can form a two-sided steel formwork side reinforcement structure through the first-level longitudinal stiffener 7 and the first-level transverse stiffener 8, which has the characteristics of a side reinforcement grid structure. In actual use, it can effectively improve the side structural strength of the steel formwork body 1 and has a good side impact resistance effect.

[0033] The secondary longitudinal stiffeners 11 and secondary transverse stiffeners 12 can form a top reinforcing structure network of the steel formwork body 1, which is used to improve the top impact resistance of the steel formwork body 1. Through the structural reinforcement on both sides and the top, the box culvert steel formwork of this utility model can have a multi-faceted reinforcement effect. Its actual structural strength is higher and its load-bearing capacity is better, and it has better performance characteristics.

[0034] In this embodiment, in order to improve the structural strength of the inner mold cavity 2 of the steel template body 1, inner reinforcing strips 13 are fixedly installed on both sides of the inner wall of the inner mold cavity 2 of the steel template body 1. The inner reinforcing strips 13 are made of the same material as the steel template body 1, thereby improving the structural strength of the inner mold cavity 2.

[0035] Working principle: When it is necessary to assemble two steel template bodies 1, the two steel template bodies 1 can be aligned and then brought into contact end to end. At this time, the end surfaces of the two steel template bodies 1 are in contact with each other. During the end-to-end contact process of the two steel template bodies 1, the assembly wedge 4 at the tail end of one steel template body 1 can be inserted into the assembly seat 3 at the front end of the other steel template body 1, thereby completing the initial assembly connection between the two steel template bodies 1.

[0036] After the assembly wedges 4 of the two steel template bodies 1 are positioned and connected to the assembly base 3, the assembly wedges 4 and the assembly holes 5 on the assembly base 3 are vertically aligned, as shown in the attached instruction manual. Figure 4As shown, bolts for assembly are then installed one by one in several aligned assembly holes 5, thereby completing the quick assembly connection between the two steel formwork bodies 1. By operating in the above manner, the quick assembly and laying of the box culvert steel formwork can be completed, improving the construction efficiency of the steel formwork.

[0037] This utility model can form a lateral reinforcement structure for steel formwork on two sides through a primary longitudinal stiffener 7 and a primary transverse stiffener 8. It has the characteristics of a lateral reinforcement grid structure. In actual use, it can effectively improve the lateral structural strength of the steel formwork body 1 and has a good lateral impact resistance effect. At the same time, the grid-like reinforcement formed by the primary longitudinal stiffener 7 and the primary transverse stiffener 8 can improve the overall compressive strength of the steel formwork body 1, so that it has a better structural bearing capacity and service stability, making it more practical and with better structural performance.

[0038] The secondary longitudinal stiffeners 11 and the secondary transverse stiffeners 12 can form a top reinforcing structure network of the steel formwork body 1, which is used to improve the top impact resistance of the steel formwork body 1. Through the structural reinforcement on both sides and the top, the box culvert steel formwork of this utility model can have a multi-faceted reinforcement effect. Its structural strength is higher and its load-bearing capacity is better when it is actually used, and it has better practical use characteristics.
