Description

Technical Field

[0001] This utility model relates to the technical field of equipment for temporary road construction, and in particular to a roadbed box for temporary road paving. Background Technology

[0002] Large construction sites are equipped with various engineering vehicles such as transport trucks and cranes. These vehicles have large carrying capacities and heavy workloads, placing high demands on the road surface, such as its firmness and flatness. Taking cranes as an example, when lifting and transporting construction materials, the vehicles must be parked stably and reinforced with outriggers. Therefore, the outriggers must also be stable and reliable. However, some construction sites are affected by geographical location, construction conditions, and weather, resulting in loose soil, severely damaged surface layers, and slippery road surfaces. This makes it difficult to guarantee the stability of parking and driving safety of construction vehicles. Therefore, to ensure construction progress and safety, sometimes roadbed boxes are laid to form temporary roads for the safe use of construction vehicles. However, most roadbed boxes currently in use cannot be directly connected to improve their relative stability. Therefore, they need to be large in size and weight to ensure stability on their own. This necessitates the use of large-tonnage cranes for lifting during paving and dismantling, increasing construction costs. Furthermore, the frequent passage of engineering vehicles generates severe vibrations and bumps, which can create large gaps between the roadbed boxes. These gaps will continue to widen over time, further reducing the stability of the engineering vehicles. When cranes use the roadbed boxes as lifting supports, the reliability of their support for the vehicles is also reduced. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a temporary roadbed box that can be interconnected after installation, which can reduce the size of the installation, thereby reducing the volume and weight, facilitating assembly, and avoiding gaps after connection, thus helping to ensure the smooth and safe passage of engineering vehicles.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a roadbed box for temporary road paving, comprising a bottom plate and a top plate arranged opposite to each other, side plates fixedly connected to the periphery of the bottom plate and the top plate, and a plurality of spaced long plates welded in parallel within the rectangular space enclosed by the bottom plate, the top plate and the side plates, with spaced short plates respectively arranged opposite to each other on both sides of each spaced long plate, and the periphery of the spaced long plate and the periphery of the spaced short plate are respectively fixedly welded to the adjacent bottom plate, the top plate and / or the side plate, and at least one pair of oppositely arranged side plates are provided with side plate connecting devices, and the side plate connecting devices are arranged one-to-one on the two side plates.

[0005] As a preferred technical solution, the top surface of the box top plate is covered with an anti-slip plate.

[0006] As a preferred technical solution, the side panel connecting device includes an installation opening on the side panel of the box, a connecting support plate protruding towards the inside of the side panel is fixedly welded in the installation opening, a connecting pin is fixedly fixed through the connecting support plate, a flange is fixedly welded to the outer end of the connecting pin, and the surface of the flange is flush with the outer surface of the side panel of the box or the side of the anti-slip plate.

[0007] As a preferred technical solution, the connecting support plate is configured as a trapezoidal folded plate and its inner surface is welded to the corresponding long or short spacer plate.

[0008] As a preferred technical solution, a hoisting protective plate with a corresponding shape is fixedly attached to the outer surface of the connecting support plate.

[0009] As a preferred technical solution, the outer corners of the hoisting protective plate are respectively set as arc corners.

[0010] As a preferred technical solution, at least one reinforcing support plate is welded to the long or short spacer plate adjacent to the connecting support plate, and the connecting pin passes through the reinforcing support plate for fixed installation.

[0011] As an improvement to the above technical solution, a weight-reducing hole is provided through the long plate and / or the short plate of the interval.

[0012] Due to the adoption of the above technical solution, the roadbed box for temporary road paving includes a bottom plate and a top plate arranged opposite each other. Side plates are fixedly connected to the periphery of the bottom plate and the top plate. A plurality of spacer plates are welded parallel within the rectangular space enclosed by the bottom plate, the top plate, and the side plates. Short spacer plates are respectively provided on both sides of each long spacer plate. The periphery of each long spacer plate and the periphery of each short spacer plate are fixedly welded to the adjacent bottom plate, the top plate, and / or the side plate. At least one pair of opposite side plates are equipped with a side plate connecting device. The plates are arranged in a one-to-one correspondence; this utility model has the following beneficial effects: the rectangular box formed by welding the bottom plate, top plate and side plate of the box is the roadbed box. The roadbed boxes can be laid in sequence to form a temporary road. By setting the long plate and short plate of the interval, the support is formed from the inside of the roadbed box, so that it can withstand the pressure generated by engineering vehicles and vehicles passing by. The side plate connecting device can realize the connection and fixation of two adjacent roadbed boxes, thereby avoiding gaps during use, making it safer and more reliable. The side plate connecting device also helps to reduce the size of the roadbed box, and the lifting and installation can be completed by a small tonnage crane, which helps to reduce the laying cost.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] like Figures 1 to 6As shown, temporary roadbed boxes are used for paving temporary roads. Multiple boxes need to be interconnected to quickly construct temporary roads on construction sites with poor road conditions, allowing for safe operation of engineering vehicles such as cranes. The boxes include a bottom plate 1 and a top plate 2 positioned opposite each other. Side plates 3 are fixedly connected to the periphery of the bottom plate 1 and the top plate 2. The bottom plate 1 rests against the ground, the top plate 2 supports construction vehicles, and the side plates 3 connect the bottom plate 1 and the top plate 2, providing support for the top plate 2. To avoid overly cluttered lines that would affect the overall presentation, ... Figure 5 The relevant internal structure of the roadbed box is not shown with dashed lines, but in its Figure 6 The enlarged view shows this.

[0023] The bottom plate 1, top plate 2, and side plate 3 of the box are fixedly welded together to form a rectangular space, creating a box-like structure. Several parallel spacer plates 4 are welded within this rectangular space to strengthen the connection between the bottom plate 1 and the top plate 2, and to provide strong support for the top plate 2, thus meeting the requirements for carrying heavy-duty engineering vehicles. Each spacer plate 4 has opposite spacer plates 5 on both sides, and the periphery of each spacer plate 4 and spacer plate 5 is fixedly welded to the adjacent bottom plate 1, top plate 2, and / or side plate 3. In this embodiment, the spacer plates 4 are arranged along the length of the top plate 2, and the spacer plates 5 are arranged along the width of the top plate 2. The orientations of both can be reversed, but both will still provide support for the top plate 2.

[0024] In this embodiment, side plate connecting devices are installed on at least one set of two oppositely arranged box side plates 3, with each side plate connecting device corresponding to the other of the two box side plates 3. The side plate connecting devices are used to connect adjacent box side plates 3, enabling the expansion of the roadbed box to form a temporary road. Furthermore, the side plate connecting devices allow for the connection and fixation of adjacent roadbed boxes, preventing gaps during use and making the system safer and more reliable. The installation of these side plate connecting devices also helps to reduce the size of the roadbed box, allowing for lifting and installation using a small-tonnage crane, thus reducing paving costs.

[0025] Specifically, the side plate connecting device includes an installation opening 6 on the side plate 3 of the box. A connecting support plate 7 protruding towards the inner side of the side plate 3 is fixedly welded into the installation opening 6. A connecting pin 8 is fixed through the connecting support plate 7. A flange 9 is fixedly welded to the outer end of the connecting pin 8, and the surface of the flange 9 is flush with the outer surface of the side plate 3. When laying temporary roads, the surfaces of the flanges 9 on two adjacent side plates 3 are abutted together. Studs pass through the corresponding screw holes on the two flanges 9, and the two flanges 9 are then connected and fixed together by the cooperation of two nuts. The operation is simple and convenient. Since the studs used for connection are relatively long, when connecting the two flanges 9, the studs can be fixed to one of the flanges 9 with nuts first. As the other side plate 3 is in place, the bolts are aligned with the corresponding screw holes, and finally, the other end of the bolts that have passed through the position is tightened with nuts.

[0026] In this embodiment, the connecting support plate 7 is configured as an isosceles trapezoidal folded plate, with its inner surface welded to the corresponding long spacer plate 4 or short spacer plate 5. A flat vertical surface is formed on the connecting support plate 7 for assembling the connecting pin 8. The flange 9 and the connecting pin 8 can also serve as lifting components for the roadbed box, used to connect the lifting rope on the crane. To prevent wear on the lifting rope, a lifting protective plate 10 with a corresponding shape can be fixedly attached to the outer surface of the connecting support plate 7, and the outer corners of the lifting protective plate 10 are respectively set as rounded corners, which can be made of rubber plates to provide a certain degree of protection for the lifting rope.

[0027] At least one reinforcing support plate 11 is welded to the long spacer plate 4 or the short spacer plate 5 adjacent to the connecting support plate 7. The connecting pin 8 is fixedly installed through the reinforcing support plate 11 to enhance the fixation of the connecting pin 8. A threaded section and a nut can also be provided at the inner end of the connecting pin 8 to prevent it from falling off during lifting and improve safety.

[0028] An anti-slip plate 12 can also be provided on the top surface of the box top plate 2, and the surface of the flange 9 can be flush with the side of the anti-slip plate 12. The protective plate can be made of checkered steel plate to prevent vehicles from slipping when passing through. Honeycomb-shaped weight-reducing holes 13 are provided through the long partition plate 4 and / or the short partition plate 5, which can reduce the weight by more than 15% while ensuring the strength of the roadbed box, making it easier to transport and lay.

[0029] In this embodiment, at the welding joints of each plate, the weld bead must not be less than 0.6 mm of the thickness of the relatively thinner plate, and not less than 6 mm, to ensure welding strength. After welding, spatter and iron oxide must be removed to ensure the aesthetics of the formed roadbed box.

[0030] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
