Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a flower basket-style suspended walkway structure. Background Technology

[0002] In the construction of deep foundation pit projects in the building industry, temporary access roads need to be built to meet the needs of workers entering and exiting the foundation pit and for emergency evacuation.

[0003] A search revealed Chinese patent CN213976734U, which discloses a long standard section, including a long standard section body. The height of the long standard section body is set to n×h meters, where n is a natural number greater than or equal to 2, and h is 2.8 to 3. The long standard section of this utility model has a height that is an integer multiple of the original short standard section. The long standard section can be hoisted and installed without the need for steps to lift and erect the tower, unlike the original standard section. Furthermore, for the same tower height, the original standard section requires multiple lifting and connection operations, while the long standard section only requires fewer hoisting operations, resulting in faster tower erection and reduced risk of tower collapse. Compared to existing standard sections, the long standard section eliminates the need for steps for lifting and erecting the tower, reducing manufacturing processes and costs. Setting the height of the long standard section as an integer multiple of the original short standard section facilitates building design and construction, improving work efficiency.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] The aforementioned patent search facilitates building design and construction. However, during the layered excavation of deep foundation pits, repeated dismantling and erection are required, reducing construction efficiency. Conventional suspended walkway structures have a single stress form and a low safety factor. Furthermore, due to the influence of complex construction sites, the use of conventional suspended walkways will be limited when there are no suitable cantilever beam anchor points around the foundation pit or when construction space is limited. Therefore, they have certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a flower basket-style suspended walkway structure, which is lightweight, has a strong load-bearing capacity, is flexible in installation, and can be adjusted in shape and size according to site requirements.

[0007] The technical solution to achieve the purpose of this utility model is: a basket-type suspended catwalk structure, including a crown beam, a waist beam and an I-beam, wherein the waist beam is located below the crown beam, and multiple I-beams are provided, and it also includes a standard catwalk section and a basket-type diagonal brace assembly;

[0008] The standard section of the bridleway includes a steel column set on one side of the crown beam, with multiple horizontal steel bars fixedly installed on the steel column, and a ladder fixedly installed inside the standard section of the bridleway.

[0009] The basket-type diagonal brace assembly includes a tie rod disposed between the crown beam, the waist beam, and the I-beam.

[0010] Preferably, multiple welding plates are welded between the I-beam and the steel column, an ear plate is fixedly installed on one end surface of the I-beam, a connecting plate is fixedly installed on one side of the I-beam, a supporting steel is fixedly installed between the connecting plate and the I-beam, and multiple high-strength bolts are threaded between the connecting plate and the waist beam.

[0011] Preferably, a high-strength nut is threaded onto one end of each high-strength screw, and an expansion head is fixedly installed on the other end of each high-strength screw. The expansion head is located inside the waist beam, and a washer is provided between the high-strength nut and the connecting plate.

[0012] Preferably, a connecting block is fixedly installed at one end of the pull rod, a high-strength bolt is threaded onto the connecting block, the connecting block is connected to the ear plate through the high-strength bolt, and turnbuckles are threaded between the pull rods.

[0013] Preferably, a connecting plate two is fixedly installed at the other end of the tie rod, and a high-strength bolt two is threaded onto the connecting plate two, and the connecting plate two is connected to the waist beam through the high-strength bolt two.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, the I-beam cantilever beam of this suspended walkway is installed on the foundation pit support structure, without occupying the ground space around the foundation pit. The tension provided by the brace can be adjusted by adjusting the basket-type diagonal brace, increasing the force distribution and thus enhancing the safety of the suspended walkway.

[0016] Secondly, depending on the length of the upper and lower fixed walkways, this utility model can be configured with two or more basket-shaped cantilevered I-beams.

[0017] This solves the problems of existing deep foundation pit layered excavation processes, which require repeated dismantling and erection, reducing construction efficiency; conventional suspended walkway structures have a single stress form and low safety factor; and are limited in use when there are no suitable cantilever beam anchor points around the foundation pit or when construction space is limited due to complex construction site conditions.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved basket-style suspended walkway structure. The technical solution of this utility model is as follows:

[0028] like Figures 1-5 As shown, a basket-type suspended walkway structure includes a crown beam 1, a waist beam 2, and an I-beam 6. The waist beam 2 is located below the crown beam 1. Multiple I-beams 6 are provided to assist in the subsequent installation of tie rods 16 and improve safety during construction. It also includes a standard walkway section 3 and a basket-type diagonal tie rod assembly 5.

[0029] The standard section 3 of the walkway includes a steel column 301 set on one side of the crown beam 1. Multiple horizontal steel bars 302 are fixedly installed on the steel column 301. A ladder 7 is fixedly installed inside the standard section 3 of the walkway to facilitate construction by workers, speed up construction and shorten the construction period.

[0030] The basket-type diagonal brace assembly 5 includes a tie rod 16 disposed between the crown beam 1, the waist beam 2 and the I-beam 6, which provides lateral support, prevents the structure from tilting or deforming, distributes the load, and enhances the overall stability.

[0031] Furthermore, multiple welding plates 4 are welded between the I-beam 6 and the steel column 301. An ear plate 8 is fixedly installed on one end surface of the I-beam 6. A connecting plate 14 is fixedly installed on one side of the I-beam 6. A supporting steel 10 is fixedly installed between the connecting plate 14 and the I-beam 6. Multiple high-strength screws 12 are threadedly installed between the connecting plate 14 and the waist beam 2. The high-strength screws 12 have strong load-bearing capacity, are suitable for high-load applications, and have good fatigue resistance, long service life, convenient installation, and high reliability.

[0032] As a further embodiment of this utility model, a high-strength nut 11 is threaded onto one end of each high-strength screw 12, and an expansion head 20 is fixedly installed on the other end of each high-strength screw 12. The expansion head 20 is located inside the waist beam 2, and a gasket 13 is provided between the high-strength nut 11 and the connecting plate 14 to expand the expansion head 20 and make it in close contact with the substrate, thereby achieving a firm connection.

[0033] Furthermore, a connecting block 15 is fixedly installed at one end of the pull rod 16, and a high-strength bolt 9 is threaded on the connecting block 15. The connecting block 15 is connected to the ear plate 8 through the high-strength bolt 9. Turnbuckles 18 are threaded between the pull rods 16, which is beneficial to adjust the length of the pull rod 16 according to the actual construction situation and improve the practicality of the device.

[0034] Furthermore, a connecting plate 17 is fixedly installed at the other end of the tie rod 16. A high-strength bolt 19 is threaded onto the connecting plate 17. The connecting plate 17 is connected to the waist beam 2 through the high-strength bolt 19, ensuring that the tie rod 16 is firmly connected to the main structure and improving stability and robustness.

[0035] The specific working method is as follows: First, during the construction of the crown beam 1, high-strength bolts 19 are installed. During the construction of the waist beam 2, high-strength threaded rods 12 with expansion heads 20 are installed. After the crown beam 1 and waist beam 2 reach a certain strength, the connecting plate 14 of the I-beam 6 is connected to the high-strength threaded rod 12. High-strength nuts 11 are used to fix the I-beam 6 to the high-strength threaded rod 12 with expansion heads 20. Next, the basket-type diagonal brace assembly 5 is installed: both ends of the brace 16 are connected to the I-beam 6 with bolts. The basket is adjusted to make the brace 16 in a non-stressed state. Then, the main body of the walkway is installed, and the standard section 3 of the walkway is installed section by section. The assembled walkway is then hoisted to the base. Inside the pit, the suspended walkway is assembled. After the walkway body is aligned, the steel columns 301 of the I-beam 6 and the standard section 3 of the walkway are connected sequentially using welding plates 4. After the suspended walkway is installed, a horizontal passageway is installed above the cap beam 1 and anchored to the ground. Finally, the turnbuckle 18 is adjusted. Based on the weight of the suspended walkway, the tension of the turnbuckle tie rod assembly 5 is calculated. By adjusting the turnbuckle 18 of the turnbuckle tie rod assembly 5, the turnbuckle tie rod assembly 5 provides a reasonable tension. In addition, for extended suspended walkways, after the pit is excavated to a certain depth, a standard section 3 of the walkway can be directly connected from below the suspended walkway.
