Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a safety passage on top of a steel casing. Background Technology

[0002] In the construction of foundations for buildings such as bridges and docks, the main functions of steel casings include protecting the foundation structure, preventing collapse, guiding construction, and isolating contaminants. Especially in the construction of bored pile foundations, steel casings prevent borehole wall collapse, protect the stability of the borehole, and provide a safe working environment for construction workers. Therefore, to ensure the safety of construction personnel, a safety passage is usually installed on top of the steel casing to prevent falls from heights and other potential hazards. The safety passage consists of transverse passages on both sides and multiple longitudinal passages. For ease of transportation, the safety passage is generally modularly designed and assembled on site. However, during assembly, due to dimensional errors in the processing of the longitudinal passages, it is impossible to guarantee that each longitudinal passage is of equal length. This can lead to problems in connecting the longitudinal passages with the transverse passages during installation. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a safety passage at the top of the steel casing, which solves the problem that due to processing errors, it is impossible to guarantee that each longitudinal passage can be connected to the transverse passages on both sides.

[0004] The technical solution adopted in this utility model is as follows:

[0005] The safety passage at the top of the steel casing includes a transverse passage and a longitudinal passage connected to the transverse passage, and also includes:

[0006] Connector plate number one is located on the inner side of the transverse channel;

[0007] Connecting seats are located at both ends of the longitudinal channel;

[0008] A sliding groove is provided at the front end of the connector.

[0009] The second connecting plate is connected to the connecting seat and is partially located in the slide groove;

[0010] Waist holes are located on the side of the connector;

[0011] Bolt #1 passes through the waist hole and mates with connecting plate #2.

[0012] The height of the chute is greater than the height of the second connecting plate, and the bottom of the connecting seat is provided with a second bolt for contacting the bottom of the second connecting plate.

[0013] Both the No. 1 connecting plate and the No. 2 connecting plate are coated with an anti-rust coating.

[0014] Both the transverse and longitudinal passages include passage panels and guardrails. The passage panels have sleeves on both sides for cooperating with the guardrails, and the sleeves have connectors for cooperating with the guardrails.

[0015] The bottom of the passage panel is provided with a support strip in the form of an I-beam.

[0016] The surface of the passage panel is provided with anti-slip texture.

[0017] Both the transverse and longitudinal passages are equipped with one-way doors that open inwards.

[0018] The beneficial effects of this utility model are:

[0019] The distance between the second connecting plate and the transverse channel is adjusted by moving the second connecting plate back and forth in the groove of the connecting seat. After the second connecting plate is adjusted, the first bolt is tightened to lock the second connecting plate, and the second connecting plate can then be connected to the first connecting plate, effectively solving the problem that the longitudinal channel cannot be connected to the transverse channel due to dimensional errors.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the safety passage at the top of the steel casing includes a transverse passage 1 and a longitudinal passage 2 connected to the transverse passage 1, and also includes:

[0029] Connector plate 3 is located on the inner side of the transverse channel 1;

[0030] Connecting seat 4 is located at both ends of the longitudinal channel 2;

[0031] Slide 5 is located at the front end of connector 4;

[0032] The second connecting plate 6 is connected to the connecting seat 4 and is partially located in the slide groove 5;

[0033] Waist hole 7 is located on the side of connector 4;

[0034] Bolt No. 8 passes through the waist hole 7 and mates with connecting plate No. 2 6.

[0035] The distance between the second connecting plate 6 and the transverse channel 1 is adjusted by moving the second connecting plate 6 back and forth in the groove of the connecting seat 4. After the second connecting plate 6 is adjusted, the first bolt 8 is tightened to lock the second connecting plate 6, and the second connecting plate 6 can be connected to the first connecting plate 3, effectively solving the problem that the longitudinal channel 2 cannot be connected to the transverse channel 1 due to dimensional errors.

[0036] In the embodiments, such as Figure 3 , Figure 4 As shown, the height of the slide groove 5 is greater than the height of the second connecting plate 6, and the bottom of the connecting seat 4 is provided with a second bolt 9 for contacting the bottom of the second connecting plate 6. The second bolt 9 can appropriately adjust the height of the second connecting plate 6 to ensure that the connecting holes of the first connecting plate 3 and the second connecting plate 6 match, facilitating installation.

[0037] In the embodiments, such as Figure 3 , Figure 4 As shown, both the first connecting plate 3 and the second connecting plate 6 are coated with an anti-rust coating 10. This prevents the connection strength between the first connecting plate 3 and the second connecting plate 6 from decreasing due to corrosion, ensuring the stability and safety of the connection between the transverse channel 1 and the longitudinal channel 2.

[0038] In the embodiments, such as Figure 1 , Figure 2 As shown, both the transverse passage 1 and the longitudinal passage 2 include a passage panel 11 and a guardrail 12. The passage panel 11 has sleeves 13 on both sides for engaging with the guardrail 12. Each sleeve 13 has a connector 14 for engaging with the guardrail 12. The connector 14 is a bolt, allowing for the disassembly of the passage panel 11 and the guardrail 12 for easy transportation.

[0039] In the embodiments, such as Figure 1 , Figure 2 As shown, the bottom of the passage panel 11 is provided with a support strip 15 in the form of an I-beam. The support strip 15 is an I-beam structure, which has good load-bearing capacity and bending resistance, and can effectively support the passage panel 11.

[0040] In the embodiments, such as Figure 5 As shown, the surface of the access panel 11 is provided with anti-slip texture 16. This prevents workers from slipping when walking on the access panel 11 and ensures their safety.

[0041] In the embodiments, such as Figure 1 , Figure 5 As shown, both the transverse passage 1 and the longitudinal passage 2 are equipped with inward-opening one-way doors 17. This prevents construction workers from falling from the edge of the passage due to negligence, slipping, or other accidents while walking in the passage.

[0042] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
