Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline network engineering construction, and particularly relates to a rapid support structure for steel formwork. Background Technique

[0002] There are various construction methods for pipeline network engineering operations. Among them, trench construction of the pipeline main body is one of the important construction methods, and trench support is an important step in trench construction of the pipeline main body. Currently, the traditional wooden cross-listing support method uses manual erection of cross-listing for support construction. In the whole implementation process of this support method, only manual operation can be carried out, and personnel need to directly enter the trench without safety protection measures for operation. When the trench depth reaches 2m or more, or in trench support operations with complex geological conditions such as soft soil, backfill soil, sand and gravel, etc., there are relatively high safety risks for the support personnel.

[0003] Therefore, combining the two requirements, a rapid support structure for steel formwork is designed, which is convenient for installation and disassembly and has a good support effect, can ensure the safety of on-site trench construction, and improve the reliability of trench support. Content of the Utility Model

[0004] The purpose of the utility model is to propose a rapid support structure for steel formwork aiming at the deficiencies of the existing technology. Based on the existing wooden cross-listing, this steel formwork support structure utilizes the characteristic that the strength of the steel skeleton itself is higher than that of the wooden cross-listing to form a rapid support structure for steel formwork. Compared with using ordinary wooden cross-listing.

[0005] The technical purpose of the utility model is achieved through the following technical solutions:

[0006] A rapid support structure for steel formwork includes a steel frame and a slide rail. Iron plates are welded on the front side and the rear side of the steel frame. Connecting frames are riveted on both sides of the opposite side of the iron plates. An adjusting mechanism is placed in the inner cavity of the connecting frame. The adjusting mechanism includes an adjusting screw rod. An adjusting tube is sleeved on the surface of the adjusting screw rod by threads. T-shaped blocks are riveted on both sides of the opposite side of the iron plates. A dust-proof cloth is riveted on the opposite side of the slide rail.

[0007] Preferably, a handle is riveted on the top of the adjusting tube, and an adjusting nut is fixedly sleeved on the surface of the adjusting screw rod.

[0008] Preferably, a pin is movably connected through the top of both sides of the connecting frame, and the pin is located on the top of the adjusting screw rod.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As a rapid support structure for steel formwork of the present utility model, as Figures 1-5 shown, this embodiment provides a rapid support structure for steel formwork, including a steel frame 1 and a slide rail 13. Iron plates 2 are welded to the front side and the rear side of the steel frame 1. Connecting frames 3 are riveted to both sides of the opposite sides of the iron plates 2. An adjusting mechanism 4 is placed in the inner cavity of the connecting frame 3. The adjusting mechanism 4 includes an adjusting screw rod 5. An adjusting tube 6 is threadedly sleeved on the surface of the adjusting screw rod 5. T-shaped blocks 14 are riveted to both sides of the opposite sides of the iron plates 2. A dust-proof cloth 15 is riveted to the opposite side of the slide rail 13.

[0025] In some embodiments, the thickness of the iron plate 2 is 1 mm - 2 mm. The steel frame 1 is made of a steel pipe with a cross-section of 50 mm * 50 mm. The number of the adjusting screw rods 5 and the adjusting tubes 6 can be increased or decreased according to the support requirements.

[0026] In some preferred embodiments, as Figure 1 and Figure 4 shown, a handle 7 is riveted to the top of the adjusting tube 6. An adjusting nut 8 is fixedly sleeved on the surface of the adjusting screw rod 5. When in use, when the adjusting screw rod 5 needs to be rotated, the user holds the handle 7 and then rotates the adjusting nut 8 with a wrench. The adjusting nut 8 drives the adjusting screw rod 5 to rotate, so that the adjusting screw rod 5 extends to the outside of the adjusting tube 6, increasing the length of the adjusting tube 6, and the support for grooves with different widths can be carried out.

[0027] In some preferred embodiments, as Figure 1 and Figure 4 shown, a pin 9 is movably connected through the top of both sides of the connecting frame 3. The pin 9 is located at the top of the adjusting screw rod 5. After the adjusting screw rod 5 is placed inside the connecting frame 3, the pin 9 is inserted into the top of both sides of the connecting frame 3, and the pin 9 limits the adjusting screw rod 5 so that it will not fall off.

[0028] In some preferred embodiments, as Figure 1 and Figure 2As shown, a vertical rod 10 is welded inside the steel frame 1. Cross rods 11 are welded on both sides of the vertical rod 10. Opposite ends of the cross rods 11 are welded to the steel frame 1. After the steel frame 1 is welded, the vertical rod 10 and the cross rods 11 are added inside it. The strength of the steel frame 1 can be increased through the vertical rod 10 and the cross rods 11, making it not prone to bending or breaking.

[0029] In some other embodiments, such as Figure 1 and Figure 5 As shown, the sliding rail 13 is slidably connected to the T-shaped block 14. A lifting ring 12 is welded to the top of the steel frame 1. After the adjacent iron plates 2 are spliced, the sliding rail 13 is sleeved on the surface of the T-shaped block 14, and then the sliding rail 13 is pressed downward. At this time, the dust-proof cloth 15 is located on the surface of the iron plate 2, so as to be able to block the gap where the iron plates 2 are spliced and prevent mud from entering the trench.

[0030] Such as Figure 1 As shown, the utility model is particularly suitable for installation and use during the construction of pipeline trenches. The steel frame 1 and the iron plate 2 are hoisted into the trench through the lifting ring 12. One side of the iron plate 2 is attached to the inner wall of the trench. Then the sliding rail 13 is sleeved on the surface of the T-shaped block 14, and the dust-proof cloth 15 further seals the connection between the iron plates 2. Then the adjusting screw rod 5 is placed inside the connecting frame 3, and the shaft pin 9 is installed on the surface of the connecting frame 3. The length of the adjusting screw rod 5 is adjusted according to the width of the trench. The user holds the handle 7 and then rotates the adjusting nut 8 with a wrench. The adjusting nut 8 drives the adjusting screw rod 5 to rotate. The adjusting screw rod 5 starts to move through the threaded connection with the adjusting pipe 6. The adjusting screw rod 5 moves outside the adjusting pipe 6, so as to adjust its length, so that one end of the adjusting screw rod 5 can be in close contact with the iron plate 2 to support it.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
