[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, embodiment 1 of the present application provides a light ditch construction formwork system, including a light plastic steel side formwork 1 and a steel bar support frame, the steel bar support frame includes transverse steel bars 2 and longitudinal steel bars 3, two longitudinal steel bars 3 are arranged at both ends of the transverse steel bars 2, and the two longitudinal steel bars 3 located on the same side of the transverse steel bars 2 are respectively used to clamp the light plastic steel side formwork 1 arranged inside and outside corresponding to one side of the ditch from the inside and outside.

[0027] By setting up a steel support frame, the linear adjustment and reinforcement of the light plastic steel side form 1 can be achieved, thereby meeting the conditions for concrete pouring, and by adopting the light plastic steel side form 1, the overall mass of the formwork is made lighter, and it can be reused after simple cleaning after demolding, without the need for grinding and rust removal, and without the need for applying release agents, thereby improving production efficiency and utilizing waste materials to process the steel support frame, with a significant cost reduction effect.

[0028] The top end of the longitudinal reinforcement 3 is vertically fixed on the transverse reinforcement 2. Specifically, the longitudinal reinforcement 3 can be directly welded to the transverse reinforcement 2.

[0029] like Figure 2 and Figure 3 As shown, in the second embodiment, a sleeve 4 is fixedly installed at the top of the longitudinal steel bar 3, and the sleeve 4 is slidably sleeved outside the transverse steel bar 2. A threaded section 5 is provided on the transverse steel bar 2 corresponding to each longitudinal steel bar 3, and a positioning nut 6 is sleeved on the external thread of the threaded section 5. The positioning nut 6 allows the longitudinal steel bar 3 to clamp the light plastic steel side form 1 through the sleeve 4. When fixing the light plastic steel side form 1, the positioning nut 6 can be rotated to displace the positioning nut 6 on the threaded section 5, and the bite between the positioning nut 6 and the threaded section 5 is used to squeeze the sleeve 4, thereby pressing the longitudinal steel bar 3 against the light plastic steel side form 1, thereby fixing the light plastic steel side form 1.

[0030] The surface of the transverse steel bar 2 is provided with a strip slide 7, and the inner wall surface of the sleeve 4 is fixed with a strip slider 8 that slides with the strip slide 7. By providing the strip slide 7 and the strip slider 8, the longitudinal steel bar 3 has a limiting effect. When the positioning nut 6 squeezes the sleeve 4 so that the longitudinal steel bar 3 fixes the light plastic steel side mold 1, the longitudinal steel bar 3 can be prevented from tilting, thereby ensuring the fixing effect.

[0031] Limiting plates 9 are fixedly arranged on both sides of the sleeve 4. When the longitudinal reinforcement 3 clamps the light plastic steel side form 1, the end of the limiting plate 9 facing the light plastic steel side form 1 contacts the top of the light plastic steel side form 1. By setting the limiting plate 9 and using the limiting plate 9 to contact the top of the light plastic steel side form 1, the limiting plate 9 can prevent the sleeve 4 from rotating in the process of the positioning nut 6 squeezing the sleeve 4 to drive the longitudinal reinforcement 3 to squeeze the light plastic steel side form 1. Then, in conjunction with the strip slider 8 and the strip slide 7, the transverse reinforcement 2 can be prevented from rotating, thereby ensuring that the longitudinal reinforcement 3 is in a vertical state.

[0032] The longitudinal reinforcement 3 is arranged corresponding to the longitudinal ribs at the opposite ends of two adjacent light plastic steel side forms 1. Such arrangement enables the longitudinal reinforcement 3 to have a sufficient contact surface with the light plastic steel side form 1 when fixing the light plastic steel side form 1, so as to improve the fixing effect of the light plastic steel side form 1.

[0033] Specifically, a locking block 10 is fixed on the longitudinal steel bar 3, and a locking groove 11 is opened at one end of the locking block 10 toward the light plastic steel side mold 1. The locking groove is arranged to be outwardly expanded, and the groove cavity of the locking groove 11 is arranged to be a rectangular structure, and the groove cavity width of the locking groove 11 is adapted to the sum of the longitudinal rib thicknesses of the two light plastic steel side molds 1.

[0034] Through the above arrangement, when the longitudinal steel bar 3 displaces to one side of the light plastic steel side form 1 and contacts the light plastic steel side form 1, the locking groove 11 will be put on the outside of the longitudinal ribs at the opposite ends of the two adjacent light plastic steel side formworks 1. Then, when the longitudinal steel bar 3 clamps the light plastic steel side formwork 1, the locking groove 11 can clamp and fix the two adjacent light plastic steel side formworks 1 in the transverse splicing direction, so that the spliced ​​light plastic steel side formworks 1 fit more closely.

[0035] like Figures 4 to 7As shown, in the third embodiment, the locking block 10 is divided from the two side walls of the locking groove 11 into a first part 10.1 located in the middle and second parts 10.2 symmetrically distributed on both sides of the first part 10.1. The first part 10.1 is fixedly mounted on the longitudinal steel bar 3, and the second part 10.2 is slidably mounted on the first part 10.1. A push rod 12 for driving the two second parts 10.2 to move relative to each other is arranged on the sleeve 4. By such arrangement, when the longitudinal steel bar 3 moves toward the light plastic steel side mold 1 and clamps the light plastic steel side mold 1, the push rod 12 squeezes the second part 10.2 by moving toward one side of the light plastic steel side mold 1, so that the two second parts 10.2 in the locking block 10 move relative to each other to clamp the longitudinal ribs of the light plastic steel side mold 1. During this process, the second part 10.2 clamps the longitudinal ribs at the opposite ends of two adjacent light plastic steel side molds 1 in the splicing direction. At this time, the direction of the clamping force applied by the second part 10.2 to the light plastic steel side mold 1 is parallel to the moving direction of the longitudinal steel bar 3, so that the clamping effect is better.

[0036] The sleeve 4 includes an inner tube 4.1, an outer tube 4.2 and a spring 4.3. The outer tube 4.2 is sleeved on one end of the inner tube 4.1 away from the light plastic steel side form 1. The spring 4.3 is arranged between the inner tube 4.1 and the outer tube 4.2, and the push rod 12 is connected to the outer tube 4.2. By making the sleeve 4 arranged as above, when the positioning nut 6 pushes the sleeve 4 to make the longitudinal steel bar 3 move toward the light plastic steel side form 1, the spring 4.3 is supported between the inner tube 4.1 and the outer tube 4.2, so that the sleeve 4 is initially longer as a whole. After the longitudinal steel bars 3 contact the light plastic steel side formwork 1, as the positioning nut 6 continues to move toward the light plastic steel side formwork 1, the positioning nut 6 causes the outer tube 4.2 to move on the inner tube 4.1 and squeeze the spring 4.3. During this process, the outer tube 4.2 will drive the top rod 12 to move and squeeze the second part 10.2, and then drive the two second parts 10.2 to clamp the longitudinal ribs at the opposite ends of the two adjacent spliced ​​light plastic steel side formworks 1 from both sides.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
