Description

Technical Field

[0001] This utility model belongs to the field of bridge structure technology, and more specifically, it relates to a quick-installation and disassembly structure for tower column crossbeam support. Background Technology

[0002] In bridge construction and temporary works, Bailey bridges are a commonly used load-bearing structure, widely applied in the construction of temporary bridges, construction trestle bridges, and support systems for large buildings, allowing users to quickly assemble structures with a certain load-bearing capacity. However, traditional tower columns and crossbeams use a steel pipe column + distribution beam + Bailey bridge structure. This support system requires considerable time for installation and dismantling, resulting in long construction periods and low efficiency. Furthermore, during construction, components are prone to loosening and falling due to vibrations, external forces, and other factors, posing a safety threat to construction personnel and equipment and reducing the safety of the construction site. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a quick-installation and dismantling structure for tower column crossbeam supports. This solves the technical problem that the traditional tower column crossbeam structure, which uses steel pipe columns, distribution beams, and Bailey beams, requires a considerable amount of time for installation and dismantling.

[0004] The purpose and effectiveness of this utility model's quick-installation and disassembly structure for a tower column beam support are achieved through the following specific technical means:

[0005] A quick-installation and dismantling structure for a tower column crossbeam support includes a Bailey beam with multiple sets of first holes. A lowering bundle passes through each of the first holes. A distribution beam is located below the Bailey beam. A crossbeam support is located between the Bailey beam and the distribution beam. The lowering bundle passes sequentially through the Bailey beam, the crossbeam support, and the distribution beam. A first nut and a second nut are respectively provided at both ends of the lowering bundle. A trestle is inserted through one end of the lowering bundle. A jack is provided at the top of the trestle, and an insert plate is provided at the bottom of the trestle.

[0006] According to a preferred embodiment, a second hole is provided on the Bailey beam, and an anti-falling cable is inserted into the second hole.

[0007] According to a preferred embodiment, one end of the anti-falling beam is connected to the Bailey beam by a nut, and the other end passes through the Bailey beam, the crossbeam support, and the distribution beam in sequence, and is fixed by a nut.

[0008] According to a preferred embodiment, the lowering bundle is composed of multiple sets of finely rolled threaded steel bars; the multiple sets of finely rolled threaded steel bars in the lowering bundle are connected by threaded connectors.

[0009] According to a preferred embodiment, the jack is provided with a shim, which is sleeved on the lowering bundle and fixed to the lowering bundle by a third nut.

[0010] According to a preferred embodiment, both the first hole and the second hole are provided with pre-embedded pipes.

[0011] According to a preferred embodiment, the insert plate has a U-shaped structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the synergy of the lowering harness and the jack, allows users to lower the entire support structure step by step through segmented extension and lowering operations. Users can control the height of the support structure by adjusting the lifting force of the jack, eliminating the need for large hoisting equipment during the lowering process and improving the flexibility of the device in confined construction environments. Simultaneously, the anti-fall harness, composed of multiple parallel precision-rolled threaded steel bars symmetrically arranged on both sides of the support structure, is secured with double nuts and buffer washers to prevent accidental falls, ensuring the device maintains stability under dynamic loads and providing users with enhanced safety.

[0014] 2. When using this device, the user can lock the lowering position of the support beam during the lowering process by using the U-shaped insert plate and the adjustable trestle. The user only needs to tighten or loosen the nuts to complete the fixation, optimizing the support adjustment process from traditional welding to mechanical assembly, thus improving the device's assembly and disassembly efficiency and reusability. Furthermore, the trestle's height is adjustable via a threaded rod at the bottom to accommodate different beam spacings, allowing the device to flexibly handle the construction needs of multiple beams and reducing the cost of customized support structures.

[0015] 3. This utility model, through the pre-embedded pipes in the first and second holes, facilitates the installation of the lowering beam and the anti-falling beam, while also protecting the surrounding concrete structure. During repeated installation and adjustment, it avoids direct wear and damage to the edges of the Bailey beam holes, extending the service life of the Bailey beam, improving the convenience of hole use and structural durability, and reducing structural safety hazards and maintenance costs caused by hole damage.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, this utility model provides a quick-installation and disassembly structure for a tower column crossbeam support, including a Bailey beam 11. Multiple sets of first holes are opened on the Bailey beam 11, and a lowering bundle 12 passes through each of the first holes. A distribution beam 13 is located below the Bailey beam 11, and a crossbeam support 14 is located between the Bailey beam 11 and the distribution beam 13. Through the arrangement of the Bailey beam 11, the lowering bundle 12, the distribution beam 13, and the crossbeam support 14, a stable support system can be constructed, improving the load-bearing capacity of the device in engineering projects. The lowering bundle 12 passes sequentially through the Bailey beam 11, the crossbeam support 14, and the distribution beam 13. A first nut 15 and a second nut 16 are respectively provided at both ends of the lowering bundle 12. Through the arrangement of the lowering bundle 12, the first nut 15, and the second nut 16, the position of the lowering bundle 12 between the Bailey beam 11, the crossbeam support 14, and the distribution beam 13 can be fixed, improving the stability of the device structure. A trestle 17 is inserted through one end of the lowering beam 12. A jack 18 is installed on the top of the trestle 17, and an insert plate 19 is installed at the bottom of the trestle 17. By setting up the lowering beam 12, the trestle 17, the jack 18 and the insert plate 19, the height of the crossbeam support 14 can be adjusted, so that the device can cope with different terrain conditions and diverse construction requirements.

[0025] like Figure 3 As shown, a second hole is provided on the Bailey beam 11, and an anti-falling harness 21 is inserted into the second hole. The Bailey beam 11, the second hole, and the anti-falling harness 21 enhance the safety of the structure, prevent components from falling, and improve the safety of the device on the construction site.

[0026] One end of the fall arrestor 21 is connected to the Bailey beam 11 via a nut, and the other end passes sequentially through the Bailey beam 11, the crossbeam support 14, and the distribution beam 13, and is secured with a nut. The fall arrestor 21 ensures a stable connection between the Bailey beam 11, the crossbeam support 14, and the distribution beam 13, improving the reliability of the fall arrestor structure. In construction scenarios, this fall arrestor design enhances the safety of the device on-site, safeguarding the lives of construction workers and ensuring the stable operation of the equipment.

[0027] The lowering bundle 12 is composed of multiple sets of finely rolled threaded steel bars; these multiple sets of finely rolled threaded steel bars are connected by threaded connectors 22. The material used to construct the lowering bundle 12, namely the finely rolled threaded steel bars, and the placement of the threaded connectors 22, allows for easy extension of the lowering bundle 12 to adapt to different height requirements, thus improving the flexibility of the device in height adjustment.

[0028] like Figure 2 , 3 As shown, the jack 18 is equipped with a washer 23, which is fitted onto the lowering bundle 12 and fixed to it by a third nut 24. In actual operation, when height adjustment is required using the jack 18, the washer 23 increases the contact area between the jack 18 and the lowering bundle 12, dispersing pressure and preventing damage to the lowering bundle 12 due to localized force concentration. Furthermore, the third nut 24 further locks the washer 23 to the jack 18, ensuring that its position remains stable and does not shift throughout the entire height adjustment process. This improves the stability of the height adjustment operation, avoids safety risks caused by device shaking or displacement during adjustment, and provides strong protection for the safety of the construction process.

[0029] Both the first and second holes are equipped with embedded pipes 25. The installation of the first hole, the second hole, and the embedded pipes 25 facilitates the installation of the lowering beam 12 and the anti-falling beam 21. The embedded pipes 25 protect the surrounding structure of the holes and prevent damage to the holes of the Bailey beam 11 during installation, thereby improving the convenience of using the holes and the durability of the structure, and extending the service life of the entire device.

[0030] like Figure 3 As shown, the insert plate 19 has a U-shaped structure, with its open end adapted to the cross-sectional shape of the lowering beam 12. The insert plate 19 facilitates installation and better fits the lowering beam 12, improving the ease of installation and fixation of the insert plate 19, and further enhancing the stability of the entire device.

[0031] The specific usage and function of this embodiment are as follows:

[0032] During concrete pouring, the first and second holes are pre-drilled on the Bailey beam 11. During installation, the lowering bundle 12, which is composed of multiple sets of precision-rolled threaded steel bars, is first installed. The first nut 15 and the second nut 16 are installed at both ends of the lowering bundle 12, and a U-shaped insert plate 19 and a pad are installed at one end. Then, a trestle 17 is installed at the end through which the lowering bundle 12 passes. A jack 18 is placed on top of the trestle 17. After the jack 18 is fitted with a washer 23, it is fixed to the lowering bundle 12 by a third nut 24. During the overall lowering process, first loosen the first nut 15, then use jack 18 to lower the crossbeam support 14 to a certain height. Tighten the first nut 15, loosen the third nut 24, and then raise jack 18 again. Repeat this cycle. When the lowering height requires extending a single precision-rolled threaded steel bar, first tighten the first nut 15, loosen the third nut 24, and extend the threaded steel bar using threaded connector 22. Then replace the higher support 17 and tighten the third nut 24, continuing the above cycle until the lowering reaches the designated position. Throughout the process, one end of the anti-falling brace 21 is connected to the Bailey beam 11 via a nut, and the other end passes through the Bailey beam 11, crossbeam support 14, and distribution beam 13 in sequence, and is secured with a nut to prevent the support from falling during lowering, ensuring construction safety. The open end of the U-shaped insert 19 is adapted to the cross-sectional shape of the lowering brace 12, facilitating installation and better securing the lowering brace 12.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
