Description

Technical Field

[0001] This utility model belongs to the technical field of bridge construction equipment, specifically relating to a steel tower bridge site construction platform. Background Art

[0002] The location of a steel tower bridge site refers to the position of the steel tower during bridge construction. Steel towers are critical load-bearing components in bridge structures such as cable-stayed bridges or suspension bridges, and their construction has a vital impact on many aspects of the entire bridge, including stress distribution, stability, and harmony with the surrounding environment.

[0003] A common method in steel tower bridge construction is to use the steel tower diaphragms as working platforms, such as... Figure 6 As shown, the steel tower diaphragm is an important component of the steel tower structure. It is a plate-like structure set perpendicular to the longitudinal axis of the steel tower, dividing the internal space of the steel tower, much like floor partitions in a building.

[0004] When placing construction equipment within the limited area of ​​the steel tower cross-section, and when the diaphragm is tilted in the actual bridge condition, the bottom surface of the equipment needs to be leveled to prevent the equipment from slipping on the diaphragm. The larger the diaphragm's angle of inclination, the greater the height difference of the leveling, and the greater the safety risk.

[0005] In addition, when erecting the next layer of steel tower, all construction equipment must be hoisted out of the current steel tower, and after the next layer of steel tower is erected, all construction equipment must be hoisted into the upper horizontal diaphragm of the erected steel tower.

[0006] It is evident that using steel tower diaphragms as work platforms not only prevents the free placement of construction equipment but also fails to effectively protect the steel tower diaphragms, posing a risk of equipment tipping over. Furthermore, frequent hoisting of construction equipment is required, resulting in significant safety and quality hazards. Utility Model Content

[0010] The platform body has several support beams at its bottom that are connected to the connecting seat, and a working surface for placing construction equipment is formed at the top of the platform body.

[0011] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0012] By setting connecting seats on the ribs of the steel tower, and connecting the connecting seats to the support beams, multiple support beams can calibrate the main body of the platform above to a horizontal position. The main body of the platform is connected and fixed to the ribs through the connected support beams and connecting seats. Construction equipment can be placed on the entire platform, providing a large area of ​​free placement for construction, and avoiding damage to the diaphragms caused by placing construction equipment on the diaphragms for a long time.

[0026] In one embodiment, a second fence is provided at the center of the base, and the second fence is spaced apart from the first fence on the periphery. The first fence and the second fence are used to tie and fix the construction equipment.

[0027] By setting up a first fence and a second fence on the base, it is easier to tie and fix the construction equipment placed on the base to the fence, thus ensuring the stability of the construction equipment.

[0028] In one embodiment, the support beam includes:

[0029] Support plate;

[0030] Several stiffening plates are provided on both sides of the supporting upright plate;

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0057] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] like Figure 1-5 As shown, the steel tower 2 bridge site construction platform provided by this utility model includes: a platform body 4, a number of support beams 5 and a number of connecting seats 1 connected to the bottom of the platform body 4.

[0059] like Figure 1 As shown, the connecting seat 1 is connected and fixed to the plate rib 3 of the steel tower 2. The steel tower 2 has plate ribs 3 spaced apart on its vertical plane. Since the plate ribs 3 originally have bolt holes, the connecting seat 1 is connected and fixed to the plate ribs 3 using the original bolt holes on the plate ribs 3.

[0060] The bottom of the platform body 4 is provided with several support beams 5 that are connected to the connecting seats 1. One support beam 5 is connected and fixed to a row of connecting seats 1. The top of the platform body 4 forms a working surface for placing construction equipment.

[0061] By setting a connecting seat 1 on the plate rib 3 of the steel tower 2, the connecting seat 1 is connected to the support beam 5. Multiple support beams 5 can calibrate the upper platform body 4 to a horizontal position. Through the connected support beam 5 and connecting seat 1, the platform body 4 is connected and fixed to the plate rib 3. Construction equipment can be placed on the entire platform body 4, providing a large area of ​​free placement for construction, and avoiding damage to the diaphragm caused by placing construction equipment on the diaphragm for a long time.

[0062] like Figure 4 As shown, the connecting seat 1 includes two base plates 101 and a top plate 102.

[0063] A first connecting hole 103 is provided on the base plate 101 for connecting with the bolt holes on the rib 3. The two base plates 101 are spaced apart and clamped on the two sides of the rib 3. The distance between the two base plates 101 is set to be consistent with the thickness of the rib 3, so that the surfaces of the two base plates 101 are respectively attached to the two sides of the rib 3. The base plates 101 are then fixed to the rib 3 using bolts or other fasteners. The top plate 102 is connected to the top of the two base plates 101. The top plate 102 is provided with a second connecting hole 104 for connecting with the support beam 5. The connecting seat 1 formed by the base plate 101 clamping and fixing the top plate 102 can ensure the connection stability with the rib 3 and the connection stability with the platform body 4. The support beam 5 at the bottom of the platform body 4 is connected and fixed to the top plate 102 through the second connecting hole 104. The platform body 4 is erected and fixed on the rib 3 by the support beam 5.

[0064] A plurality of first connecting holes 103 are arrayed on the base plate 101, and the bolt holes on the corresponding plate rib 3 are also arrayed. By arraying multiple first connecting holes 103, the connection strength between the connecting seat 1 and the plate rib 3 is improved, and the stability of the connection between the connecting seat 1 and the plate rib 3 is guaranteed.

[0065] To facilitate fine-tuning of the connecting seat 1 and the plate rib 3 in the horizontal direction, the first connecting hole 103 is a horizontally arranged elongated hole. By setting the first connecting hole 103 as an elongated hole, the connecting seat 1 can be adjusted in the horizontal direction when connected to the plate rib 3, thereby improving the adaptability of the assembly.

[0066] To facilitate fine-tuning of the support beam 5 and the connecting seat 1 along the length of the support beam 5, the second connecting hole 104 is an elongated hole along the length of the support beam 5, so that the position of the support beam 5 can be adjusted along the length of the support beam 5 when the support beam 5 and the connecting seat 1 are connected.

[0067] Furthermore, the major axes of the first connecting hole 103 and the second connecting hole 104 are orthogonal to each other.

[0068] Specifically, if Figure 2 As shown, the support beam 5 includes: a support plate 501, several stiffening plates 502 and several diagonal bracing plates 503.

[0069] The support plate 501 can be made of I-beams or other components. Its top can be detachably connected to the bottom of the platform body 4 by means of fasteners such as bolts, or it can be fixedly connected to the bottom of the platform body 4 by welding.

[0070] Several stiffening plates 502 are provided on both sides of the support plate 501, while several diagonal bracing plates 503 are provided at the corners of the side of the support plate 501 and the bottom of the platform body 4, thereby improving the structural strength of the entire support plate 501, strengthening the structural strength of the top and bottom of the support plate 501, and enhancing the connection strength with the platform body 4.

[0071] In this embodiment, several support plates 501 are spaced apart, and the height of the support plates 501 gradually increases to balance the inclination of the top surface of the steel tower 2 bridge site. By setting support plates 501 with gradually increasing height at the bottom of the platform body 4, the top of the platform body 4 can be adjusted to be horizontal, ensuring the stability of the placement of construction equipment on the platform body 4.

[0072] In this embodiment, as shown in FIG3, the platform body 4 includes: a base 401, a first fence 402, and a ladder 403.

[0073] The bottom of the base 401 is connected to the support beam 5. The first fence 402 is set at the top edge of the base 401. On the one hand, the first fence 402 can play a protective role to protect the safety of construction personnel on the platform body 4. On the other hand, the first fence 402 can also be used as a medium to improve the binding of equipment placed on the platform body 4. The first fence 402 has at least one gap 405. The ladder 403 is set on the outside of the first fence 402 corresponding to the gap 405 of the first fence 402. The ladder 403 is fixed on the outside of the first fence 402, which makes it convenient for personnel to climb and move between the top and bottom of the platform body 4.

[0074] Furthermore, to improve the stability of the numerous construction devices on the platform body 4, a second fence 404 is provided at the center of the base 401. The second fence 404 is spaced apart from the first fence 402 on the periphery. The first fence 402 and the second fence 404 are used to tie and fix the construction devices. By setting the first fence 402 and the second fence 404 on the base 401, the construction devices placed on the base 401 can be more easily tied and fixed to the fences, ensuring the stability of the placement of the construction devices.

[0075] To facilitate the hoisting of the entire construction platform, the platform body 4 is provided with several lifting lugs 6. There are four lifting lugs 6 arranged in a quadrilateral on the platform body 4.

[0076] like Figure 5 As shown, during the specific installation, first, the connecting seat 1 is firmly bolted to the steel tower 2 plate rib 3, then the construction equipment is placed on the platform body 4, and then the platform body 4 is hoisted and firmly bolted to the connecting seat 1 through the lifting lug 6, and then the ladder 403 is firmly bolted to the platform body 4.

[0077] After the construction of this section of steel tower 2 is completed, first dismantle ladder 403, then lift the main platform 4 along with the construction equipment away. During this process, the construction equipment does not need to be unloaded. Finally, dismantle connecting seat 1. After the next section is erected, the assembly sequence of this device is the same as the assembly sequence during its first use.

[0078] This method of operation only requires connecting and fixing the device to the existing bolt holes on the steel tower 2 itself using high bolts. This provides a platform for placing bridge construction equipment, and the platform is horizontal without any tilt, which will not damage the structure of the steel tower 2, reduce production costs and labor intensity, and improve production efficiency.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
