Description

Technical Field

[0001] This utility model relates to the field of roadbed engineering construction support technology, and in particular to a separate roadbed rainwater grate cover support. Background Technology

[0002] In road construction, to better facilitate rainwater drainage, it is necessary to construct rainwater drainage and guiding structures in the roadbed, including rainwater grates on both sides of the roadbed. The installation of rainwater grates is usually carried out after the road surface paving is completed. However, most roads are now asphalt pavements. During the pavement compaction process, space needs to be reserved for the installation of rainwater grates without the need for additional material. Without proper positioning and restraint, this can lead to material falling off, uneven edges requiring cutting and leveling, which is time-consuming and labor-intensive. Therefore, existing technologies have implemented positioning and restraint devices to improve the construction effect of rainwater grates. For example, Chinese patent CN212895899U discloses a positioning device for rainwater grates used in bridges, including a frame with a positioning plate inside. The frame and positioning plate are connected by a support rod. An operating groove is opened in the middle of the positioning plate, and a limiting cylinder is connected to the bottom of the positioning plate. The limiting cylinder has adjusting screws from the inside out, and threaded holes that mate with the adjusting screws are provided on the limiting cylinder. The positioning of the bridge drainage grates is completed simultaneously with the bridge deck paving. Once the paving is finished, the grates can be installed directly without manual cutting, saving manpower and resources, effectively improving construction efficiency and shortening the construction period. However, the positioning device for these bridge drainage grates is overly complex and cumbersome to operate, hindering practical application in construction. Therefore, the structure of auxiliary devices for drainage grates during road paving construction needs further improvement and optimization. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a separable roadbed rainwater grate cover bracket, comprising an upper cover plate and a support frame. The upper part of the support frame forms a groove for assembling the upper cover plate, which is installed in the groove. The upper cover plate and the support frame are restricted and positioned by a limiting positioning structure. The upper cover plate or the support frame is provided with an operating structure for separating the upper cover plate from the support frame.

[0004] As a further explanation of this utility model, the support frame is a rectangular frame structure, including reinforcing ribs arranged horizontally and / or vertically along the support frame.

[0005] Furthermore, the limiting positioning structure includes corner angle steel disposed at the corner of the support frame, the corner angle steel protruding towards the upper cover plate to restrict the horizontal movement of the upper cover plate.

[0006] Furthermore, the limiting positioning structure includes a plurality of limiting posts disposed on the upper cover plate, which, together with the supporting frame, form a limiting engagement to restrict the horizontal movement of the upper cover plate.

[0007] Furthermore, the operating structure is an operating handle or an operating through hole provided on the upper cover plate.

[0008] Furthermore, the upper cover plate is provided with a receiving groove, and the operating handle is disposed in the receiving groove.

[0009] Furthermore, the upper cover plate is provided with a second cover plate that covers the receiving groove.

[0010] The beneficial effects of this utility model are:

[0018] Example:

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] As attached Figure 1-5 As shown in the figure, a detachable roadbed rainwater grate cover bracket of this embodiment includes an upper cover plate 1 and a support frame 2. The upper part of the support frame 2 forms a groove for assembling the upper cover plate. The upper cover plate 1 is installed in the groove. The upper cover plate 1 and the support frame 2 are adapted in size and can be detachably assembled and connected. The upper cover plate 1 and the support frame 2 are restricted and positioned by a limiting positioning structure. The upper cover plate 1 or the support frame 2 is provided with an operation structure for separating the upper cover plate 1 from the support frame 2. This embodiment of the separable roadbed rainwater grate cover plate bracket adopts a separable structure design of upper cover plate 1 and support frame 2. During construction, it can be erected on the position of the rainwater grate for asphalt pavement paving without any other operations. After initial compaction, the upper cover plate 1 is removed, and after secondary compaction, the support frame 2 is removed to install the rainwater grate. It can be reused, eliminating the step of manually cutting asphalt and saving costs. The support frame 2 can be made of angle steel welded together, and the upper cover plate 1 is made of steel plate structure. The overall bracket structure has a high load-bearing capacity and can meet the mechanical compaction requirements during asphalt pavement paving. The structure is simple, sturdy, durable, easy to install and dismantle, and easy to operate.

[0022] Rainwater grates are generally rectangular in structure. Therefore, in a preferred embodiment, the supporting frame 2 is a rectangular frame structure, including reinforcing ribs arranged horizontally and / or vertically along the supporting frame 2. In practical applications, the horizontal reinforcing ribs 3 can be spaced ≤300mm to prevent longitudinal bending of the frame during asphalt paving (deflection controlled ≤L / 250, where L is the frame span). The vertical reinforcing ribs can be selected according to actual size requirements, and are generally optional in cases of large widths. They can be designed as "X-shaped" diagonally intersecting ribs to enhance the frame's torsional resistance, especially suitable for repeated compaction by heavy road rollers (≥12 tons). As described above, the main load-bearing structure of the split roadbed rainwater grate cover support in this embodiment is the supporting frame 2. The frame body, horizontal reinforcing ribs 3, and vertical reinforcing ribs are formed by welding 50×50×5mm angle steel together to form the supporting frame 2.

[0023] See the appendix for details. Figure 1 As shown, in this embodiment, corner steel 4 is provided at the corner of the support frame 2. The corner steel 4 protrudes towards the upper cover plate 1 to restrict the horizontal movement of the upper cover plate 1. When in use, after the upper cover plate 1 is closed, the upper surface of the split roadbed rainwater grate cover support forms a relatively flat surface. In practical applications, the protrusion height of the corner steel 4 is equal to the thickness of the upper cover plate 1, forming an "L-shaped" retaining edge to prevent the lateral pressure during asphalt paving construction from causing the upper cover plate 1 to slide laterally (limiting force ≥3kN).

[0024] As another embodiment, referring to the accompanying drawings, the limiting positioning structure consists of a plurality of limiting posts 5 disposed on the upper cover plate 1. These limiting posts 5, in conjunction with the support frame 2, restrict the horizontal movement of the upper cover plate 1. Specifically, the limiting posts 5 are distributed and abut against the inner side of the support frame 2 at different positions, thereby limiting the relative movement between the upper cover plate 1 and the support frame 2, effectively restricting the horizontal movement of the upper cover plate 1 and achieving the same functional effect as the above embodiment. In this embodiment, the plurality of limiting posts 5 do not only have one way of forming a limiting engagement with the support frame 2 to restrict the horizontal movement of the upper cover plate 1. Besides abutting against the inner side of the support frame 2 to form a relative movement restriction, a plurality of positioning holes can also be drilled on the support frame 2. During assembly, the limiting posts 5 are aligned with the positioning holes and inserted to achieve relative movement restriction between the upper cover plate 1 and the support frame 2. Alternatively, in some embodiments, the plurality of limiting posts 5 are distributed on both sides of the transverse reinforcing rib 3, which can also achieve relative movement restriction between the upper cover plate 1 and the support frame 2. It can be seen that the relative movement restriction between the upper cover plate 1 and the support frame 2 is not limited to the specific implementation shown in the accompanying drawings.

[0025] To facilitate the rotation and folding of the split-type roadbed rainwater grate cover support by construction workers, as one implementation method, see Appendix. Figure 1 As shown, the operating structure is an operating handle 6 installed on the upper cover plate 1. The operating handle 6 is a rotatable handle. During the asphalt pavement paving construction, the operating handle 6 is rotated to a horizontal position that fits against the surface of the upper cover plate 1 to avoid damaging the operating handle 6 during paving compaction. After the initial compaction of the asphalt pavement, the operating handle 6 is rotated to a vertical position perpendicular to the upper cover plate 1. The upper cover plate 1 can be pulled out and removed by using the operating handle 6 as the point of force. At this time, the support frame 2 has not yet been removed to provide support and restraint for the secondary compaction construction. After the secondary compaction is completed, the support frame 2 is removed and the rainwater grate is installed. Similarly, in this embodiment, the operating structure is not limited to the above-mentioned operating handle 6. In practical applications, the operating structure can also be an operating through hole 7 installed on the upper cover plate 1. In this embodiment, the surface flatness of the upper cover plate 1 can be better guaranteed, which helps to avoid the upper cover plate 1 being deformed or damaged during asphalt pavement paving construction. In this embodiment, after the initial compaction is completed, a simple hook tool can be used to pull the upper cover plate 1 out and remove it through the operating through hole 7. It can be seen that the specific structural settings of the operation structure are not limited to the specific implementation shown in the attached figures.

[0026] In the preferred embodiment, see Appendix Figure 1 As shown, a receiving groove 8 is provided on the upper cover plate 1, and the operating handle 6 is located in the receiving groove 8. During the construction of asphalt pavement, the operating handle 6 will not be crushed or damaged, thus forming a protective effect on the operating handle 6.

[0027] In the above embodiments, in order to ensure the surface flatness of the upper cover plate 1, the shape of the receiving groove 8 can be set to match the shape of the operating handle 6, or see the attached diagram. Figure 3 As shown, a second cover plate 9 is provided on the upper cover plate 1 to cover the receiving groove 8. During the asphalt pavement construction, the operating handle 6 is retracted and the second cover plate 9 is closed, so that the upper cover plate 1 forms a flat surface. After the initial compaction of the asphalt pavement construction, the second cover plate 9 is opened, and the upper cover plate 1 can be removed using the operating handle 6, thereby improving the practical application and operation effect of the split roadbed rainwater grate cover support.

[0028] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. In short, all changes made within the scope of the independent claims of the present invention are within the scope of protection of the present invention.
