Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a slope adjustment device for temporary trestle bridges and a temporary trestle bridge. Background Technology

[0002] A temporary trestle is a bridge structure built to meet short-term or transitional needs, providing safe passage for personnel, equipment, and materials, and can be dismantled or redeployed to other locations after the project is completed. The rate of change of the trestle's height along its length is called its longitudinal slope. The presence of a longitudinal slope increases the structural complexity and construction difficulty of a trestle; therefore, longitudinal slopes are generally avoided when building temporary trestles. However, in some mountainous areas and other scenarios, it is unavoidable to avoid longitudinal slopes.

[0003] A trestle bridge consists of vertical support columns, crossbeams, and longitudinal beams. Crossbeams extend laterally along the trestle bridge and are fixed to the top of the vertical support columns. Multiple crossbeams are distributed longitudinally along the trestle bridge to support the longitudinal beams. Longitudinal beams extend longitudinally along the trestle bridge and are fixed above the crossbeams. For trestle bridges with a longitudinal slope, currently, support pads are mainly welded and fixed to the crossbeams at the locations where they support the longitudinal beams. When dismantling the trestle bridge, these support pads cannot be removed from the crossbeams. Since the height and inclination angle of the support pads are determined by the longitudinal slope of the trestle bridge, and the height of the support pads varies at different locations along the longitudinal direction of the trestle bridge, the dismantled crossbeams can only be used to rebuild a trestle bridge with the same longitudinal slope, limiting its application.

[0004] Therefore, how to solve the problem that the crossbeams of temporary trestle bridges with longitudinal slopes are limited in their re-application scenarios after dismantling has become an important technical problem for those skilled in the art to solve. Utility Model Content

[0008] According to the present invention, a slope adjustment device for a temporary trestle bridge is provided, wherein two slots are distributed at intervals along the extension direction of the crossbeam, and the extension direction of each slot is perpendicular to the bearing direction of the crossbeam and the extension direction of the crossbeam.

[0009] The slope adjustment device for a temporary trestle bridge provided by this utility model further includes: A limiting member is detachably disposed at the open end of the slot, the limiting member being adapted to restrict the sliding of the protrusion along the extension direction of the slot.

[0010] According to the present invention, a slope adjustment device for a temporary trestle bridge is provided, wherein the base is provided with an overlapping groove on the side away from the crossbeam, and the open end of each slot corresponds to one overlapping groove, and the overlapping groove is connected to the slot. The limiting component includes: A limiting rod, one end of which is embedded in the overlapping groove that communicates with one of the slots, and the other end of which is embedded in the overlapping groove that communicates with the other slot.

[0011] The slope adjustment device for a temporary trestle bridge provided by this utility model further includes: A fastener is disposed on the base and threadedly connected to the base. The axis of the fastener is perpendicular to the extension direction of the slot. A first end of the fastener extends to the outside of the base, and a second end of the fastener is adapted to abut against the ramp block.

[0012] According to the present invention, a slope adjusting device for a temporary trestle bridge includes: A first support plate and a second support plate are stacked and detachably connected, with the second support plate located on the side of the first support plate away from the base; Wherein, along the extension direction of the crossbeam, the first support plate protrudes from the second support plate, and the protrusion of the first support plate from the second support plate forms the protruding ridge. The surface of the second support plate away from the first support plate is set at an angle to the bearing surface of the crossbeam, and the bearing surface of the crossbeam is perpendicular to the bearing direction of the crossbeam.

[0013] According to the present invention, a slope adjustment device for a temporary trestle bridge is provided, wherein at least two first support plates are provided, each of which is adapted to be located on the same side of the second support plate, and at least one first support plate protrudes from the second support plate along the extension direction of the crossbeam.

[0014] According to the present invention, a slope adjustment device for a temporary trestle bridge is provided, wherein each of the first support plates and the second support plates is provided with a connecting hole, and each of the first support plates and the second support plates is fastened together by connecting bolts.

[0016] This utility model provides a slope adjustment device for temporary trestle bridges, which is installed at the intersection of the crossbeams and longitudinal beams of the temporary trestle bridge.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1 to 3 This invention describes a slope adjustment device for temporary trestle bridges.

[0025] like Figures 1 to 3 As shown in the figure, the slope adjustment device for a temporary trestle provided in this embodiment of the present invention is installed at the intersection of the crossbeams and longitudinal beams of the temporary trestle. Multiple crossbeams are provided, arranged side-by-side and spaced apart, and the longitudinal beams intersect with each of the crossbeams. Multiple slope adjustment devices for the temporary trestle are correspondingly installed at multiple positions on the longitudinal beams of the temporary trestle. These multiple slope adjustment devices support the longitudinal beams of the temporary trestle at different positions, and the support height of the different slope adjustment devices on the longitudinal beams is different, so that the slope of the longitudinal beams is consistent with the target longitudinal slope of the temporary trestle.

[0026] The slope adjustment device for temporary trestle bridges provided in this embodiment of the utility model includes a base 1 and a slope block 2.

[0027] Specifically, the base 1 is fixed to the crossbeam, and the slope block 2 is detachably installed on the base 1. The slope block 2 is used to support the longitudinal beam.

[0028] The slope block 2 has a first surface and a second surface along the bearing direction of the crossbeam. The first surface and the second surface are set at an angle. The first surface is in contact with the base 1, and the second surface is in contact with the longitudinal beam.

[0029] This configuration, which fixes the base 1 to the crossbeam of the temporary trestle, ensures the stability of the slope adjustment device used for the temporary trestle. Slope blocks 2 are installed on the base 1 to support the longitudinal beams of the temporary trestle. The angle between the first and second surfaces of slope block 2 is determined based on the longitudinal slope of the temporary trestle, thus supporting the longitudinal beams. Slope blocks 2 are detachably connected to the base 1. After the temporary trestle is dismantled, slope blocks 2 can be separated from the crossbeam. When the crossbeam is reused to build a trestle, the angle between the first and second surfaces of slope block 2 is determined based on the longitudinal slope of the trestle to be built. Slope blocks 2 with corresponding angles between their first and second surfaces can be selected or manufactured. The original slope blocks 2 do not restrict the re-application scenarios of the crossbeam, solving the problem in related technologies where the re-application scenarios of the crossbeams of temporary trestle bridges with longitudinal slopes are limited after dismantling.

[0030] It should be noted that after the slope adjustment device for the temporary trestle provided in this embodiment is installed between the crossbeams and longitudinal beams of the temporary trestle, it is also necessary to use U-bolts to fasten the longitudinal beams and crossbeams of the temporary trestle together to ensure the stability of the temporary trestle.

[0031] In this embodiment of the invention, two slots 3 are arranged side by side on the base 1, with the two slots 3 facing each other. A protruding ridge is formed on the side of the slope block 2 facing each slot 3, and the protruding ridge can extend into the slot 3, allowing the base 1 to support the slope block 2.

[0032] By engaging the slot 3 with the protrusion, the protrusion can be prevented from dislodging from the slot 3 along the load-bearing direction of the crossbeam, thereby ensuring the stability of the slope block 2 and the base 1 along the load-bearing direction of the crossbeam.

[0033] At least one of the two ends of the slot 3 is open, and the protrusion can be inserted into the slot 3 from the open end of the slot 3. By sliding the slope block 2 relative to the base 1, the protrusion can be fully inserted into the slot 3, which facilitates the installation of the slope block 2 on the base 1.

[0034] In a specific embodiment, the two slots 3 can be spaced apart along the extension direction of the crossbeam, and the extension direction of each slot 3 can be perpendicular to the bearing direction and the extension direction of the crossbeam.

[0035] Specifically, the base 1 can be configured as a U-shaped frame. The base 1 includes a pair of first supports and a second support. The axes of the pair of first supports are parallel to each other. The second support is disposed at the first end of the pair of first supports, and the two ends of the second support are respectively fixed to the first ends of the pair of first supports. A slot 3 is provided on the facing surfaces of the first supports. One end of the slot 3 extends to the end of the first support that connects to the second support, and the other end of the slot 3 extends to the end of the first support away from the second support and passes through the end face of the first support away from the second support.

[0036] In a further embodiment, the slope adjustment device for the temporary trestle also includes a limiting member, which is detachably disposed at the open end of the slot 3. The limiting member can abut against the end of the protrusion to restrict the protrusion from sliding along the extension direction of the slot 3.

[0037] This configuration ensures the stability of the slope block 2 and the base 1 in a direction perpendicular to the extension direction of the crossbeam, preventing the slope block 2 from falling off the open end of the slot 3.

[0038] In this embodiment, to facilitate the installation of the limiting component, an overlapping groove 4 is provided on the side of the base 1 away from the crossbeam. The overlapping groove 4 is located at the open end of the slot 3. Each open end of the slot 3 corresponds to an overlapping groove 4. The overlapping groove 4 penetrates the side wall of the slot 3 away from the crossbeam so that the overlapping groove 4 is connected to the slot 3.

[0039] The limiting component includes a limiting rod 5, one end of which is embedded in an overlapping groove 4 that communicates with one of the slots 3, and the other end of which is embedded in an overlapping groove 4 that communicates with another slot 3.

[0040] The interaction between the limiting rod 5 and the side wall of the overlapping groove 4 can limit the positional displacement of the limiting rod 5 and the base 1, ensuring the positional stability of the limiting rod 5, and thus ensuring the positional stability of the slope block 2.

[0041] In a further embodiment, the slope adjustment device for the temporary trestle also includes a fastener 6, which is disposed on the base 1 and threadedly connected to the base 1. The axis of the fastener 6 is perpendicular to the extension direction of the slot 3, the first end of the fastener 6 extends to the outside of the base 1, and the second end of the fastener 6 is used to abut against the slope block 2.

[0042] By applying torque to the first end of fastener 6, fastener 6 can be rotated. The rotation of fastener 6 relative to base 1 allows the second end of fastener 6 to move closer to or further away from slope block 2. After adjusting slope block 2, fastener 6 is tightened so that the second end of fastener 6 presses against slope block 2. Through the interaction between fastener 6 and base 1, and the interaction between the second end of fastener 6 and slope block 2, the swaying of slope block 2 relative to base 1 can be further limited, thus further determining the positional stability of slope block 2.

[0043] The fastener 6 mentioned above may be, but is not limited to, bolts or screws.

[0044] In this embodiment of the invention, the slope block 2 is configured as a multi-layered superimposed structure.

[0045] Specifically, the slope block 2 includes a first support plate and a second support plate. The second support plate is stacked on top of the first support plate and is detachably connected. The second support plate is located on the side of the first support plate away from the base 1.

[0046] Along the extension direction of the crossbeam, the first support plate protrudes beyond the second support plate, and a ridge is formed at the point where the first support plate protrudes beyond the second support plate. Specifically, the dimension of the first support plate along the extension direction of the crossbeam can be larger than the dimension of the second support plate along the extension direction of the crossbeam.

[0047] For the first support plate, the surface of the first support plate away from the base 1 and the surface of the first support plate close to the base 1 are parallel to each other and perpendicular to the bearing direction of the crossbeam. The first support plate provides stable support for the second support plate.

[0048] For the second support plate, the surface of the second support plate furthest from the first support plate is angled relative to the bearing surface of the crossbeam, and the bearing surface of the crossbeam is perpendicular to the bearing direction of the crossbeam. The inclination angle of the surface of the second support plate furthest from the first support plate relative to the bearing surface of the crossbeam needs to be determined based on the longitudinal slope of the trestle bridge.

[0049] The slope block 2 is set as a separate first support plate and second support plate. For trestle bridges with different longitudinal slopes, the first support plate can be used universally. It is only necessary to process or select the second support plate with the corresponding tilt angle according to the longitudinal slope of the trestle bridge.

[0050] In this embodiment, at least two first support plates are provided, and each first support plate can be located on the same side of the second support plate. The required number of first support plates can be selected to be stacked with the second support plate according to the specific situation.

[0051] When the crossbeams are reused after the temporary trestle is dismantled, and the longitudinal slope of the new trestle differs from that of the original trestle, it is necessary to determine the distance between the lower surface of the longitudinal beam corresponding to the crossbeam's position and the upper surface of the crossbeam, based on the crossbeam's location and the new trestle's longitudinal slope. Combining this with the dimensions of the second support plate along the crossbeam's load-bearing direction and the dimensions of each first support plate along the crossbeam's load-bearing direction, the required number of first support plates can be determined. This eliminates the need for further processing of the first support plates, making it more adaptable.

[0052] When selecting at least two first support plates, at least one first support plate should protrude beyond the second support plate along the extension direction of the crossbeam.

[0053] Specifically, one of the first support plates can protrude from the second support plate along the extension direction of the crossbeam, or all the first support plates can protrude from the second support plate along the extension direction of the crossbeam. The specific dimensions can be determined based on the dimensions of the slot 3 along the load-bearing direction of the crossbeam.

[0054] For the detachable connection of the first support plate and the second support plate, connection holes can be provided on each of the first support plate and the second support plate, and the first support plate and the second support plate can be fastened together by connecting bolts 7.

[0055] Multiple connecting holes are provided on both the first support plate and the second support plate. The multiple connecting holes are distributed at intervals along the circumference of the first support plate and at intervals along the circumference of the second support plate.

[0056] It should be noted that the first support plate, the second support plate, the base 1, and the limiting components mentioned above can all be made of stainless steel plates of a certain thickness to ensure the load-bearing capacity of the slope adjustment device used for temporary trestle bridges.

[0057] On the other hand, this utility model embodiment also provides a temporary trestle, including the slope adjustment device for a temporary trestle provided in any of the above embodiments. The slope adjustment device for a temporary trestle provided in any of the above embodiments realizes the separation of the slope block 2 from the crossbeam of the temporary trestle, removing the limitation of the slope block 2 on the reuse of the crossbeam. Therefore, the longitudinal slope of the temporary trestle in this embodiment can be adjusted by replacing the slope block 2, which can be recycled and is suitable for scenarios with different requirements for longitudinal slope, and has strong adaptability. The derivation process of the beneficial effects of the temporary trestle in this utility model embodiment is largely similar to the derivation process of the beneficial effects of the slope adjustment device for a temporary trestle, so it will not be repeated here.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
