Description

Technical Field

[0001] The utility model relates to the technical field of support structures, and particularly relates to a support structure for setting a gantry crane on an open-cut structure. Background Art

[0002] With the continuous development of urbanization in the peripheral areas of modern cities and the construction of urban rail transit, the rapid transportation system covering the city is gradually expanding to the suburbs. Compared with underground stations controlled by factors such as ground buildings, road networks, and construction costs in the city center, elevated stations have obvious advantages: low construction cost, fast construction speed, wide field of vision, good passenger perception and comfort, good fire-fighting and rescue conditions in case of emergencies, no need for ventilation systems, small energy consumption for air conditioning and lighting, and greatly saved operation energy consumption. Therefore, as a by-product of effective measures to improve urban transportation and promote the green, low-carbon, and sustainable development of the city, the planning and design of urban rail transit elevated stations have received more and more attention.

[0003] However, when constructing elevated stations, there will be situations where the elevated stations cross the open-cut structures on the ground, such as in the section of the access line of the parking lot. It is not convenient to set up a gantry crane through the existing support devices, and it is also very difficult for the existing support devices to meet the stress requirements. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a support structure for setting a gantry crane on an open-cut structure to solve the problems proposed in the background art.

[0005] To solve the above technical problems, the technical solutions adopted by the utility model are as follows.

[0006] The support structure for setting a gantry crane on an open-cut structure includes a support structure body for straddling the open-cut structure. The support structure body includes a number of truss monomers arranged side by side and fixedly connected for straddling the open-cut structure, and I-beams arranged at intervals along the length direction of the support structure body at the top for supporting the gantry crane track. Each I-beam is erected vertically on the top of each truss monomer along the width direction of the support structure body; the truss monomer includes a flat rectangular frame for straddling the open-cut structure. At both ends of the two sides of the flat rectangular frame arranged along the straddling direction, an equal-angle steel diagonal brace is respectively arranged. A number of equal-sided right-angle steel diagonal braces are sequentially arranged between the two equal-angle steel diagonal braces; the corner ends of the equal-angle steel diagonal brace and the equal-sided right-angle steel diagonal brace are both arranged downward and connected to the bottom beam of the flat rectangular frame. The top ends of the two equal-long sides of the equal-angle steel diagonal brace and the equal-sided right-angle steel diagonal brace are both connected to the top beam of the flat rectangular frame; vertical braces are respectively arranged on the equal-angle steel diagonal brace and the equal-sided right-angle steel diagonal brace, which are vertically arranged between the top beam and the bottom beam of the flat rectangular frame and bisect the corner ends of the equal-angle steel diagonal brace or the equal-sided right-angle steel diagonal brace; an inverted M-shaped brace is also arranged on the equal-sided right-angle steel diagonal brace and connected between the equal-sided right-angle steel diagonal brace and the top beam of the flat rectangular frame.

[0007] Preferably, the corner end of the equal-angle steel diagonal brace is an acute angle.

[0008] Preferably, the equal-angle steel diagonal braces and the equal-sided right-angle steel diagonal braces are sequentially connected end to end along the arranged direction.

[0009] Preferably, four identical equilateral right-angled triangles are formed between each inverted M-shaped brace and the top beam of the corresponding equal-sided right-angle steel diagonal brace and the flat rectangular frame.

[0010] Due to the adoption of the above technical solutions, the technical progress obtained by the present utility model is as follows.

[0011] Through the arrangement of a number of truss monomers fixedly arranged side by side and including a flat rectangular frame, an equal-angle steel diagonal brace, an equal-sided right-angle steel diagonal brace, a vertical brace and an inverted M-shaped brace, the present utility model can not only support the gantry crane set on the open-cut structure, but also meet the requirements of stress and reaction force.
