Description

Technical Field

[0001] This invention belongs to the field of steel beam support technology, and in particular relates to a support for erecting steel beams of large-span truss structures. Background Technology

[0002] In the construction of bridge steel beams, the most common method is to erect temporary scaffolds. In complex terrain or where existing roads cannot be temporarily occupied, it is necessary to increase the span of the scaffolds to cross the complex terrain and increase the longitudinal spacing of the steel pipe piles. However, this also leads to an increase in the span of the longitudinal distribution beams and a decrease in bending resistance. It is necessary to increase the steel type of the longitudinal distribution beams or to make a custom box structure to improve the strength and stiffness of the longitudinal distribution beams. This results in a significant increase in the self-weight of the longitudinal distribution beams and the entire scaffold, which not only makes the installation and dismantling of the scaffolds difficult, affecting the construction quality and progress, but also increases construction costs and safety risks, and the lifting costs are also relatively high. Summary of the Invention

[0003] In view of this, the present invention aims to propose a support for the erection of steel beams in large-span truss structures, so as to solve the problem of structural strength and weight balance when the span of the distribution beam increases in the existing temporary support for steel beam erection.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A support frame for erecting steel beams of a large-span truss structure includes steel pipe piles, transverse connecting components, and longitudinal connecting components;

[0006] The steel pipe piles are arranged in a rectangular shape with four piles evenly spaced. The two steel pipe piles in the longitudinal direction are connected by a longitudinal connecting component, and the two steel pipe piles in the transverse direction are connected by a transverse connecting component.

[0007] The longitudinal connection assembly includes an upper longitudinal truss and a lower longitudinal truss. The upper longitudinal truss and the lower longitudinal truss are connected by diagonal braces. Two diagonal braces are provided at the left and right ends of the longitudinal connection assembly, and the two diagonal braces are arranged in a figure-eight shape. The left and right ends of the upper longitudinal truss are provided with protrusions that can cooperate with the top of the steel pipe pile. The upper longitudinal trusses on the two steel pipe piles are connected by crossbeams. At least three crossbeams are arranged at intervals along the length of the upper longitudinal truss.

[0008] The transverse connection assembly includes an upper transverse truss and a lower transverse truss, the upper transverse truss being configured corresponding to the upper longitudinal truss, and the lower transverse truss being configured corresponding to the lower longitudinal truss.

[0009] Furthermore, the steel pipe pile is provided with a pile cap that mates with the protrusion.

[0010] Furthermore, the chords of the upper longitudinal truss, lower longitudinal truss, upper transverse truss, and lower transverse truss are all made of double H-beams, and the vertical and diagonal members are all made of round steel pipes.

[0011] Furthermore, the upward-sloping end of the diagonal brace corresponds to the connection between the vertical member and the diagonal member in the upper longitudinal truss, and the downward-sloping end corresponds to the connection between the lower longitudinal truss and the steel pipe pile.

[0012] Furthermore, the crossbeam includes two spaced-apart H-beams connected by a connector.

[0013] Furthermore, the connector is provided corresponding to the protrusion on the longitudinal beam.

[0014] Furthermore, the connector is a cuboid structure that extends between the two flanges of the H-beam and connects to the H-beam.

[0015] Compared with existing technologies, the large-span truss structure steel beam erection support described in this invention has the following advantages:

[0016] This invention provides a large-span truss structure steel beam erection support, which has the advantages of simple structure, easy construction, light weight, good applicability, and high structural stability. By using a truss structure to replace the longitudinal distribution beams of traditional supports, it serves as both the upper load-bearing structure and the longitudinal connection system. The structure has a clear stress distribution, small deformation, and is easier to erect steel beams. All truss members are made of conventional materials, resulting in low cost. Compared with traditional large-span supports, this erection support can support a larger span, uses less material, and allows for separate fabrication and on-site welding of individual members. It is convenient and quick to hoist, install, and dismantle, accelerating the construction progress, enhancing construction safety, and is suitable for various complex terrain environments.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0023] A support system for erecting steel beams in a large-span truss structure, such as... Figure 1 and Figure 2 As shown, the system includes steel pipe piles 1, transverse connecting components, and longitudinal connecting components. Four steel pipe piles 1 are evenly arranged in a rectangular pattern. Two longitudinal steel pipe piles 1 are connected by longitudinal connecting components, and two transverse steel pipe piles 1 are connected by transverse connecting components.

[0024] The aforementioned longitudinal connection assembly includes an upper longitudinal truss 2 and a lower longitudinal truss 3. The upper longitudinal truss 2 and the lower longitudinal truss 3 are connected by diagonal braces 4. Two diagonal braces 4 are provided at the left and right ends of the longitudinal connection assembly, and the two diagonal braces 4 are arranged in a figure-eight shape. The upper longitudinal truss 2 is provided with protrusions 5 at both ends of the upper longitudinal truss 2 that can cooperate with the top of the steel pipe pile 1. The upper longitudinal trusses 2 on the two steel pipe piles 1 are connected by crossbeams 6. At least three crossbeams 6 are provided at intervals along the length direction of the upper longitudinal truss 2.

[0025] For example, both the upper longitudinal truss 2 and the lower longitudinal truss 3 can be fixed to the steel pipe pile 1 using conventional methods such as welding. One end of the diagonal brace 4 can also be welded and fixed to the upper longitudinal truss 2, and the other end can be welded and fixed to the lower longitudinal truss 3. By using two diagonal braces 4 with an "eight"-shaped structure, the structural strength of the longitudinal connecting assembly can be effectively improved, ensuring that the longitudinal connecting assembly can stably connect the two longitudinal steel pipe piles 1.

[0026] In practical applications, three, four or more crossbeams 6 can be set at intervals. Two crossbeams 6 are set at the two ends of the upper longitudinal truss 2 respectively, and the remaining crossbeams 6 are set at intervals along the length of the upper longitudinal truss 2. The front and rear ends of each crossbeam 6 can be welded and fixed to the front and rear upper longitudinal trusses 2 respectively, so as to realize the connection and fixation of the front and rear upper longitudinal trusses 2, which is conducive to improving the overall structural strength and stability of this kind of support frame.

[0027] The aforementioned transverse connection assembly includes an upper transverse truss 10 and a lower transverse truss 11. The upper transverse truss 10 is configured to correspond to the upper longitudinal truss 2, and the lower transverse truss 11 is configured to correspond to the lower longitudinal truss 3. For example, the upper transverse truss 10 and the lower transverse truss 11 can also be fixedly connected to the steel pipe pile 1 using conventional methods such as welding. By configuring the upper transverse truss 10 to correspond to the upper longitudinal truss 2 and the lower transverse truss 11 to correspond to the lower longitudinal truss 3, a stable and reinforced structure can be formed on the erection support without significantly increasing the weight of the erection support.

[0028] Preferably, the steel pipe pile 1 is provided with a pile cap 7 that mates with the protrusion 5. Exemplarily, the pile cap 7 is fixed to the steel pipe pile 1, and multiple reinforcing plates are fixed around the pile cap 7 to improve its structural strength. By providing the pile cap 7, the structural strength and support area at the top of the steel pipe pile 1 can be improved, ensuring that the steel pipe pile 1 can be more stably connected to the protrusion 5 on the upper longitudinal truss 2. Furthermore, the crossbeam 6 can also be provided corresponding to the pile cap 7, thereby enabling the longitudinal connecting assembly to form a composite reinforced structure at the end of the steel pipe pile 1, thereby improving the structural strength and deformation resistance of the end of the steel pipe pile 1.

[0029] Preferably, the chords of the upper longitudinal truss 2, lower longitudinal truss 3, upper transverse truss 10, and lower transverse truss 11 are all made of double-section H-beams 8, while the vertical and diagonal members are all made of round steel pipes. By using double-section H-beams 8 as chords and round steel pipes as vertical and diagonal members, the structural weight of the longitudinal and transverse connecting components can be controlled while ensuring structural strength.

[0030] Preferably, the upward-sloping end of the diagonal brace 4 corresponds to the connection between the vertical member and the diagonal member in the upper longitudinal truss 2, and the downward-sloping end corresponds to the connection between the lower longitudinal truss 3 and the steel pipe pile 1. By adopting the above arrangement, a stable trapezoidal structure can be formed between the diagonal brace 4, the upper longitudinal truss 2, and the lower longitudinal truss 3, which can still have high structural strength and stability when using long longitudinal connection components.

[0031] Preferably, the crossbeam 6 includes two spaced-apart H-beams 8 connected by a connector 9. Exemplarily, the connector 9 corresponds to the protrusion 5 on the longitudinal beam, and the connector 9 can be fixed to the H-beams 8 using conventional methods such as welding.

[0032] In practical applications, the connector 9 is a cuboid structure that extends between the two flanges of the H-beam 8 and connects to it. By using a cuboid connector 9, the connector 9 itself has high structural strength and stability. When combined with two H-beams 8, it can form a beam 6 with a large supporting area. Moreover, this beam 6 is relatively lightweight. By arranging multiple connectors 9 at intervals along the length of the beam 6 and placing connectors 9 at the protrusions 5, not only can the structural strength of the beam 6 be further improved, but the structural strength at the connection between the beam 6 and the upper longitudinal truss 2 can also be improved.

[0033] This type of support structure mainly consists of a horizontal beam 6, a truss structure, steel pipe piles 1, diagonal braces, and a connecting system. The four steel pipe piles 1 are connected by longitudinal and transverse connecting components. The chord of the upper longitudinal truss 2 is made of double-section H-beams 8 and is placed on top of the steel pipe piles 1, welded to the pile caps 7 of the steel pipe piles 1 to form a whole. The lower chord is connected to the pile body of the steel pipe piles 1. The vertical and diagonal members of each truss structure are round steel pipes, connecting the upper and lower chords. The two truss sections are connected by a connecting system. Simultaneously, diagonal braces 4 (e.g., steel pipes) are installed below the upper longitudinal truss 2, and the diagonal braces 4 are connected to the lower longitudinal truss 3 below. By aligning the diagonal braces 4 with the diagonal members on the longitudinal truss, the load is transferred to the diagonal braces 4 through the diagonal members, and then to the steel pipe piles 1 through the diagonal braces 4. The horizontal load is borne jointly by the longitudinal and transverse connecting components. Furthermore, stiffening plates can be welded to the force transmission joints for local reinforcement as needed.

[0034] This invention provides a large-span truss structure steel beam erection support, which has the advantages of simple structure, easy construction, light weight, good applicability, and high structural stability. By using a truss structure to replace the longitudinal distribution beams of traditional supports, it serves as both the upper load-bearing structure and the longitudinal connection system. The structure has a clear stress distribution, small deformation, and is easier to erect steel beams. All truss members are made of conventional materials, resulting in low cost. Compared with traditional large-span supports, this erection support can support a larger span, uses less material, and allows for separate fabrication and on-site welding of individual members. It is convenient and quick to hoist, install, and dismantle, accelerating the construction progress, enhancing construction safety, and is suitable for various complex terrain environments.
